napasyam ubhayam mune
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
O Vyasadeva, at that time, being exceedingly overpowered by feelings of happiness, every part of my body became separately enlivened. Being absorbed in an ocean of ecstasy, I could not see both myself and the Lord.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Spiritual feelings of happiness and intense ecstasies have no mundane comparison. Therefore it is very difficult to give expression to such feelings. We can just have a glimpse of such ecstasy in the words of Sri Narada Muni. Each and every part of the body or senses has its particular function. After seeing the Lord, all the senses become fully awakened to render service unto the Lord because in the liberated state the senses are fully efficient in serving the Lord. As such, in that transcendental ecstasy it so happened that the senses became separately enlivened to serve the Lord. This being so, Narada Muni lost himself in seeing both himself and the Lord simultaneously.
