Adhyathma Ramayana is essentially a Puranic work demonstrating the inquisitiveness of Parvati and clear, unambiguous explanation by Shiva. But in the orthodox circles of Rama devotees, the Adhyatama Ramayana is considered to be a Mantra-sastra, a sacred book, each stanza of which is revered as a Mantra (mystic syllable) and devoutly repeated in a ceremonial way. And Shiva continues the story of Sri Rama to his beloved Parvati
Hearing the news of the birth of a son, King Dasharatha was in bliss with divine joy. To all those servants who told the news of son’s birth; He gifted new cloths, ornaments and plenty of wealth. As per the orders of the Guru Vasishta, he performed the ritual of birth and also meditated afterwards.
To Kaikeyi a son was born the next and to Sumithra twins sons were born. Dasaratha w also performed ritual of birth to all the children. The citizens who witnessed this divine serendipity shed tears of joy. Charity to countless Brahmins and innumerable Sadhus was given in Cattle, gold, jewels, cloths, land etc. Even the chief of heaven lord Indra had a grand festival to celebrate the Avatara of Rama on earth and gained much punya.
Guru Vasishta noticed that all sentient beings of all of all the worlds were joyous and merry and the dark infant had an extremely powerful attractive power, so the first born son of Dasharatha was named RAMA. The guru foresaw that the second son was going to be an expert administrator, he was named BHARATHA. The third son born of Sumitra had all the features of good qualities (Lakshanas), therefore he was named LAKSMANA. In the younger twin, Vasishta foresaw the quality of annihilation of all enemies, so the last son was named SATRUGNA.
After giving these names to all his four sons, King Dasharatha lived happily along with his three wives.
