yadÄ mana upÄdÄya
yad yad rūpaṠbubhūṣati
tat tad bhaven mano-rÅ«paá¹
mad-yoga-balam ÄÅ›rayaḥ
yadÄ - when; manaḥ - the mind; upÄdÄya - applying; yat yat - whatever; rÅ«pam - form; bubhūṣati - one desires to assume; tat tat - that very form; bhavet - may appear; manaḥ-rÅ«pam - the form desired by the mind; mat-yoga-balam - My inconceivable mystic potency, by which I manifest innumerable forms; ÄÅ›rayaḥ - being the shelter.
This perfection is called kÄma-rÅ«pa, or the ability to assume any form that one desires, even the form of a demigod. The pure devotees absorb their minds in a particular type of service to Lord Kṛṣṇa and thus gradually assume a spiritual body for an eternal life of bliss and knowledge. Thus anyone who takes to the process of chanting the holy names of Kṛṣṇa and follows the regulative principles of human life can acquire the ultimate perfection of kÄma-rÅ«pa, assuming an eternal, spiritual body in the kingdom of God.
