The prime symptom of pure devotional service is constant chanting, hearing, and remembrance of the holy name. Mixed devotional service, as we have previously discussed, is devotional service adulterated by karma (fruitive desire) and jñāna (attachment to knowledge). Such devotional service is often impeded by the particular situation or association a person finds himself in. But there is never any impediment to pure devotional service. Perfect realization of the Supreme Lord does not occur until one is firmly situated in unalloyed devotional service. Lord Kṛṣṇa confirms this in the Bhagavad-gītā (18.55): bhaktyā mām abhijānāti yāvān yaś cāsmi tattvataḥ. "One can understand Me as I am, as the Supreme Personality of Godhead, only by pure devotional service." And in verse 8.14 the Lord mentions the primary characteristic of this pure devotional service:
- ananya-cetāḥ satataṁ
- yo māṁ smarati nityaśaḥ
- tasyāhaṁ sulabhaḥ pārtha
- nitya-yuktasya yoginaḥ
For one who always remembers Me without deviation, I am easy to obtain, O son of Pṛthā, because of his constant engagement in devotional service.
Undeviating concentration on the Supreme Lord is the first sign of pure devotion. In other words, a pure devotee is one who wards off all desires and thoughts not related to unflinching devotional service to the Supreme Lord. Many spiritual stalwarts have commented upon pure devotional service. For example, Śrīla Rūpa Gosvāmī, the foremost of the great spiritual preceptors in the time of Śrī Caitanya Mahāprabhu, wrote in his Bhakti-rasāmṛta-sindhu (Bhakti-rasāmṛta-sindhu 1.1.11):
- anyābhilāṣitā-śūnyaṁ
- jñāna-karmādy-anāvṛtam
- ānukūlyena kṛṣṇānu-
- śīlanaṁ bhaktir uttama
- (CC Madhya 19.167)
One should render transcendental loving service to the Supreme Lord Kṛṣṇa favorably and without desire for material profit or gain through fruitive activities or philosophical speculation. That is called pure devotional service.
