After Rama’s departure to the forest, Dasharatha lies in his bed with a wailing Kaushalya. He suddenly remembers an incident which had occurred in the past. He narrates to Kaushalya about how, by accident, he had killed a young boy named Shravan mistaking him to be an elephant. Dashratha who was then a crown prince had gone hunting on the banks of River Sarayu. He was an expert in hunting by determining the direction of sound and heard the gurgle of an animal drinking water. Mistaking it to be an elephant Dasharatha shot the arrow. He became mortified when he heard a human cry as the arrow found its target. Dasharatha hurried there to find a boy lying sprawled on the banks of the river with an arrow lodged in his chest. The boy rebukes Dashratha for his unrighteous act and demands that he pull the arrow out of his chest.[9] He also tells him to take the pitcher of water to his blind parents who must be waiting for him.

Real reason behind keikeyi boon and bharat installing paduka in throne instead of ram idol
we all know keikeyi asked two boon ,With one boon Kaikeyi got Rama banished to the forest for fourteen years and with the other, she asked that Bharat be made the crown prince.
Its reason- Shravankumar's grandfather was Sage Dhoumya and his parents were Ratnavali and Sage Ratna. Sage Ratna was the royal priest of the kingdom of Nandigram ruled by King Ashvapati. Kaikeyi was the daughter of King Ashvapati. Sage Ratna had taught Kaikeyi all the scriptures and had also warned her that Dasharath's children would not be able to ascend the throne and that if they did ascend it within fourteen years after him, then the Raghu dynasty would be destroyed. To prevent this mishap, Sage Vasishtha told Kaikeyi to ask Dasharath for two boons, by one of which she sent Rama into exile for fourteen years and by the other asked Bharat to rule the kingdom because she knew that as long as Rama lived, Bharat would never ascend the throne. It is on the advice of Sage Vasishtha, that Bharat installed Rama's paduka (wooden footwear) instead of His idol, on the throne. If instead of thepaduka an idol was installed on the throne, then by the rule that sound, touch, form, taste and odour all coexist, the effect would have been just as if Rama had ascended the throne. The original Valmiki Ramayan contains three verses (shlokas) in this context. However some researchers feel that those who rewrote the Ramayan after 1228 A.D. omitted these.

'Asking for the paduka' means 'placing the head on the feet' or 'complete surrender'. When Bharat asked for Rama's padukathe latter gave them to him. The former carried them placing them on his head such that the big toes faced the front. Then he installed them on the throne and worshipped them. Since then the custom of worshipping paduka of the spiritually evolved began.

After Rama's departure, king Dasharatha, unable to bear the grief, passes away.

SHRAVAN KUMAR PARENTS STORY
When Shantvarkumar Sharma and his wife, Gyanvati, find out they are unable to conceive, they pray for years to Bhagwan Shri Brahma, who eventually appears before them, blesses them, tells them they will soon be proud parents of a devoted son, but warns them not to see him or else they will lose their vision. True enough, a son, Shravankumar, is born, but barely after a month after his birth, the couple break their promise, see him, and become blind. One day at the riverbank, Gyanvati finds that her son is missing, but he is eventually brought back to them unharmed by none other than Maharaja Dashrath, who has been childless for years. Shantvar and Gyanvati bless him with not one but four sons. Years later Shravankumar has grown up and is very devoted to his parents, he even prefers to worship them instead of God, much to chagrin of Devi Maa Maya, who decides to test his devotion. When he finds out that it was because of him they lost their vision, he undertakes to take them on a holy Trithyatra (prilgrimage) so as to restore their vision, he decides to carry them in a palanquin,instead of a chariot offer by Dashrath, and they share many adventures including getting blessed by Bhagwan Shri Shiv himself. On the last leg of their pilgrimage, Dashrath is hunting a man-eating tiger, while Shravan has gone to the riverbank to get some water for his thirsty parents. Dashrath thinks that the tiger is drinking water, shoots it, and instead kills Shravan. When a horrified Dashrath takes the water to his parents, they curse him that his dead body will never be carried by his sons, and he will be separated from his most beloved son. Soon after this both of them die, leaving Dashrath to atone for his sin - a sin that will result in the reincarnation of Bhagwan Shri Vishnu himself as his son, Bhagwan Shri Ram - who will be separated from him to satisfy a whim of Dashrath's wife, Kaikeyi, thus leading to epic Ramayan..

YUDDHA KANDA 121 TO 128
RETURN TO AYODYA & AFTER

121) Rama prepares to leave for Ayodhya. Even though Vibhishana requests Rama to remain at Lanka for some more time and receive his hospitality, Rama gently refuses to do so, adding that he needs to proceed to Ayodhya quickly, to see his mothers, brothers and people there. Vibhishana arranges the aerial car, Pushpaka to transport Rama and others to Ayodhya.

122) Rama commands Vibhishana to honour the monkeys with gold and precious stones. When Vibhishana has honoured them with the gifts, Rama along with Lakshmana and Seetha ascend the aerial car. When the monkeys and Vibhishana request Rama to permit them to accompany in the aerial car upto Ayodhya to witness his coronation-ceremony, Rama gladly permits them to do so. All of them start on their aerial journey in Pushpaka, the wonderful aerial car which can accommodate all, spaciously.

123) In the course of their flight to Ayodhya, Rama shows to Seetha, the whole City of Lanka, the battle-field where Ravana and other demons were killed, Nala-Setu the bridge which was built across the ocean, Mount Mainka, Setu-bandha (where the construction of the bridge was started), Mount Rishyamuka, Pampa River, Janasthana-forest, Panchavati, Godavari river, the hermitage of sage-Agastya, the hermitage of Atri and Anasuya, Mount Chitrakuta, Yamuna-river, the hermitage of Bharadwaja, Ganga-river, Sarayu-river and finally the City of Ayodhya.

124) Rama, travelling in the aerial car towards Ayodhya, lands at the hermitage of Bharadwaja the sage. When Rama enquires of Bhardwaja about the welfare of Ayodhya-City, Bharata and his mothers. Bharadwaja informs Rama about their welfare. Further, the sage informs that by virtue of his asceticism, he could know everything about the exploits of Rama from the day he left Ayodhya, till he destroyed Ravana. Then, Rama seeks a boon from Bharadwaja, asking him to make the trees on the route to Ayodhya, to bear fruit in the off-season for which the sage grants the boon. Thereupon, the troops of monkeys feasted on those fruits at will.

125) Rama asks Hanuma to proceed to Shringaberapura and communicate to Guha about his welfare and also to know the appropriate path to Ayodhya. Rama also asks Hanuma to go to Ayodhya and communicate to Bharata about his welfare and also the previous happenings at the forest and at Lanka, including the abduction of Seetha and her restoration, by killing Ravana in battle. Rama also asks Hanuma to inform Bharata, about their arrival at the proximity of Ayodhya, along with Sugreeva and Vibhishana. Accordingly, Hanuma approaches Guha and Bharata in Nandigrama and informs the pleasant news about the welfare of Rama as well as his impending return to Ayodhya. Bharata is overjoyed on hearing the glad tidings from Hanuma and offers him a number of valuable gifts, for having communicated the agreeable news to him.

126) Hanuma recounts to Bharata, broad details relating to the soujourn of Rama, Seetha and Lakshmana in the forest from the day Bharata takes wooden sandals of Rama, till the day Ravana is killed.

127) Bharata, after hearing the good news from Hanuma about the arrival of Rama, calls Shatrughna and commands him to make appropriate arrangements for the reception of Rama in the City of Ayodhya. Bharata departs with all others, for Nandigrama to receive Rama. The aerial car lands at Nandigrama. Bharata welcomes Rama and others, by embracing them and by greeting them joyously. Rama too offers his salutations to all his mothers, who come to receive him. Then, Bharata brings Rama’s wooden sandals and places them below the feet of Rama. Rama commands Pushpaka, the aerial car to return to Kubera, the lord of riches to whom it originally belonged.

128) At the request of Bharata to take back the kingdom of Ayodhya, Rama accepts the offer and sits on a seat. Bharata and Rama take their bath and get adorned for the occasion. Rama, mounting on an excellent chariot, sallies forth on a procession in the city accompanied by Bharata, Shatrughna, Lakshmana and Vibhishana. Nine thousand elephants follow the procession, with Sugreeva and other monkeys mounted on them. Some attendants and musicians with their musical instruments walk in front of Rama's procession. The citizens of Ayodhya host flags on every house. Rama returns to his paternal palace in Ayodhya. Sugreeva orders four of his monkeys to bring water from four oceans in jars given to them. Some monkeys brought water from five hundred rivers, as also from the four oceans for the purpose of the ceremony. Vasishta along with other brahmins as priests caused Rama to be consecrated with that water. The virgins, ministers, warriors, merchants, the four gods as well as other gods sprinkled sap of all kinds of herbs on Rama. Vasishta and other priests officiating the coronation-ceremony adorned Rama with an auspicious and charming crown. Then, Rama gives away presents to the priests as well as Sugreeva and Angada. Rama presents a pearl-necklace to Seetha and Seetha presents that necklace in turn to Hanuma. Rama further gives away presents to Vibhishana, Sugreeva, Jambavan and others on the occasion. Rama bids farewell to monkeys. The glory of the epic is complemented in the end by Valmiki.
