pravṛddha-bhāvo ’śru-kalākulo muner
dadhāra mūrdhnā caraṇaṁ hṛdā hareḥ
This is a sign of associating with great devotees. A devotee takes instructions from a liberated soul and is thus overwhelmed by ecstasy from transcendental pleasure. As stated by Prahlāda Mahārāja:
naiṣāṁ matis tāvad urukramāṅghriṁ
spṛśaty anarthāpagamo yad-arthaḥ
niṣkiñcanānāṁ na vṛṇīta yāvat
One cannot become a perfect devotee of the Lord without having touched the lotus feet of a great devotee. One who has nothing to do with this material world is called niṣkiñcana. The process of self-realization and the path home, back to Godhead, means surrendering to the bona fide spiritual master and taking the dust of his lotus feet on one’s head. Thus one advances on the path of transcendental realization. Vidura had this relationship with Maitreya, and he attained the results.
