Srila Rupa Goswami said that one must associate with devotees to cultivate faith. So how does that faith happen in association? In devotee association, one hears about Krishna. When one hears about Krishna constantly, his or her desire or taste to Krishna and His devotees (Krishna katha) goes on increasing. What is the result of one whose taste to hear about Krishna increases? His faith on Krishna increases. What is the symptom of such a faith on Krishna?
The symptom of faith on Krishna (bhakti) is twofold. This was told by Sage Kavi (one of the nine yogendras) to King Nimi. Sage Kavi said direct experience of the Supreme Lord (pareśānubhava) and detachment (virakti) from worldly things simultaneously occur to one who is in pure Krishna consciousness. This is a good litmus test to see if truly we are making progress in spiritual life.
Detachment from worldly things or virakti means one’s understanding, enthusiasm, loyalty and faith upon the people, things and relationships of this world gradually reduce and eventually die out completely and instead be replaced with increased understanding, enthusiasm, loyalty and faith of Krishna and His pure devotees. Both has to happen simultaneously. To lose faith in the confidence of people of this world (including our well-wisher, friend and family) is our true test to faith in Krishna. Because both cannot go hand in hand.
When we make that transition of faiths, truly our journey back home back to Krishna is set, in other words, we would have attained mukti from material entanglement.
