When a devotee is completely purified, he becomes anyābhilāṣitā-śūnya. 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 Kṛṣṇa consciousness, he no longer has any material activities, for his body is spiritualized. Advancement in Kṛṣṇa 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 Śrī Caitanya Mahāprabhu. In this regard, Śrīla Madhvācārya writes as follows:
- tad-bhāva-bhāvaḥ tad yathā svarūpaṁ bhaktiḥ
- kecid bhaktā vinṛtyanti gāyanti ca yathepsitam
- kecit tuṣṇīṁ japanty eva kecit śobhaya-kāriṇaḥ
The ecstatic condition of devotional service was completely exhibited by Śrī Caitanya Mahāprabhu, who sometimes danced, sometimes cried, sometimes sang, sometimes remained silent, and sometimes chanted the holy name of the Lord. That is perfect spiritual existence.
