(Srila Prabhupada on the Bowery, 1966)
"Kṛṣṇa said that 'When I make one especially favored, then I take away all his riches to make him niṣkiñcana.' Niṣkiñcana means one becomes almost poverty-stricken. Nobody cares for him. Then he become fully surrendered to Kṛṣṇa. Just like Narottama dāsa Ṭhākura says,
hā hā prabhu nanda-suta, vṛṣabhānu-sutā-juta,
koruṇā karoho ei-bāro,
narottama-dāsa koy..., koruṇā...,
nā ṭheliho rāṅgā pāy,
tomā bine ke āche āmāra
(Hari Hari Biphale 4)
This position is very nice, niṣkiñcana. 'I have lost everything. I am now not cared by my family, my friends. So everything I have lost. Therefore I am forced to come to You, surrender. So don't kick me, kick me out. Please give me shelter, because I have no other shelter.' Tomā bine ke āche āmāra: 'There is nobody else to take my care except Your Lordship.' This is called niṣkiñcana.
So actually that is the position. So long we shall think that 'For my protection, this arrangement is there for my protection. This arrangement is there,' that is not niṣkiñcana. Niṣkiñcana means when I'll think..., I'll be actually under the understanding that 'I have no other protection except Kṛṣṇa,' and then I fully surrender, that is the best qualification for Kṛṣṇa consciousness. Therefore it is said, naivārhaty abhidhātuṁ vai tvām: 'Unto You.' 'Who are You?' Akiñcana-gocaram: 'You can be understood only by a person who has lost everything.' Who has lost everything."
