In the material world, every conditioned soul changes his material body again and again, but when the spirit soul is purified of all material coverings, there is no longer a chance of his accepting a material body. Such a soul then remains in his original, spiritual identity, a state that is possible to achieve only by understanding Krsna in truth through the practice of Krsna consciousness. As Krsna says in the Bhagavad-gita (4.9),

Only when one regains his original spiritual body can he enter into the spiritual kingdom. As far as the rasa-lila pastimes of the Lord are concerned, it is futile for one who is within the material world to attempt to imitate the Lord's dances.. One has to attain a spiritual body like that of a gopi to enter into the pastimes of the rasa-lila. In the nayam sukhapo verse, the devotees are referred to as bhaktimat, that is, fully engaged in devotional service and devoid of material contamination. One cannot enter into Krsna's rasa-lila dance simply by artificially imitating it or artificially thinking oneself a sakhi and dressing up like one. Krsna's rasa-lila dance is completely spiritual. It has nothing to do with material contamination; therefore no one can enter into this pastime by artificial, material means. That is the instruction of the nayam sukhapo verse, and it must be strictly understood.
