SB 7.7.36
tada puman mukta-samasta-bandhanas
tad-bhava-bhavanukrtasayakrtih
nirdagdha-bijanusayo mahiyasa
bhakti-prayogena samety adhoksajam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The devotee is then freed from all material contamination because he constantly thinks of the Lord’s pastimes and because his mind and body have been converted to spiritual qualities. Because of his intense devotional service, his ignorance, material consciousness and all kinds of material desires are completely burnt to ashes. This is the stage at which one can achieve the shelter of the Lord’s lotus feet.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
When a devotee is completely purified, he becomes anyabhilasita-sunya. In other words, all of his material desires become zero, being burnt to ashes, and he exists either as the Lord’s servant, friend, father, mother or conjugal lover. Because one thinks constantly in this way, one’s present material body and mind are fully spiritualized, and the needs of one’s material body completely vanish from one’s existence. An iron rod put into a fire becomes warmer and warmer, and when it is red hot it is no longer an iron rod but fire. Similarly, when a devotee constantly engages in devotional service and thinks of the Lord in his original Krsna consciousness, he no longer has any material activities, for his body is spiritualized. Advancement in Krsna consciousness is very powerful, and therefore even during this life such a devotee has achieved the shelter of the lotus feet of the Lord. This transcendental ecstatic existence of a devotee was completely exhibited by Sri Caitanya Mahaprabhu. In this regard, Srila Madhvacarya writes as follows:
tad-bhava-bhavah tad yatha svarupam bhaktih
kecid bhakta vinrtyanti gayanti ca yathepsitam
kecit tusnim japanty eva kecit sobhaya-karinah
The ecstatic condition of devotional service was completely exhibited by Sri Caitanya Mahaprabhu, who sometimes danced, sometimes cried, sometimes sang, sometimes remained silent, and sometimes chanted the holy name of the Lord. That is perfect spiritual existence.
