Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sukadeva Gosvami said: Thereafter, the Supreme Personality of Godhead, Lord Ramacandra, accepted an acarya and performed sacrifices [yajñas] with opulent paraphernalia. Thus He Himself worshiped Himself, for He is the Supreme Lord of all demigods.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sarvarhanam acyutejya. If Acyuta, the Supreme Personality of Godhead, is worshiped, then everyone is worshiped. As stated in Srimad-Bhagavatam (4.31.14):
yatha taror mula-nisecanena
trpyanti tat-skandha-bhujopasakhah
pranopaharac ca yathendriyanam
tathaiva sarvarhanam acyutejya
“As pouring water on the root of a tree nourishes the trunk, branches, twigs and leaves, and as supplying food to the stomach enlivens the senses and limbs of the body, worshiping the Supreme Personality of Godhead satisfies the demigods, who are part of that Supreme Personality.” Performing yajña involves worshiping the Supreme Lord. Here the Supreme Lord worshiped the Supreme Lord. Therefore it is said, bhagavan atmanatmanam ije: the Lord worshiped Himself by Himself. This does not, of course, justify the Mayavada philosophy, by which one thinks himself the Supreme Personality of Godhead. The jiva, the living entity, is always different from the Supreme Lord. The living entities (vibhinnamsa) never become one with the Lord, although Mayavadis sometimes imitate the Lord’s worship of Himself. Lord Krsna meditated upon Himself every morning as a grhastha, and similarly Lord Ramacandra performed yajñas to satisfy Himself, but this does not mean that an ordinary living being should imitate the Lord by accepting the process of ahangrahopasana. Such unauthorized worship is not recommended herein.
