Therefore Caitanya Mahāprabhu said, niṣkiñcanasya bhagavad-bhajanonmukhasya. Bhagavad-bhajana, to become devotee, Kṛṣṇa conscious, is meant for niṣkiñcanasya, one who does not possess anything in the material world. That does not mean he should be poverty-stricken. No. He should know it fully that "Nothing belongs to me; everything belongs to Kṛṣṇa. I am simply His servant, that's all." This is called akiñcana. If I think that "Keeping Kṛṣṇa in front, let me possess some material things," that is another cheating. That is not... Akiñcana. You should be fully conscious, that "Everything belongs to Kṛṣṇa and nothing to us." Then Kṛṣṇa becomes your suhṛt. He takes charge, how your benefit will be there, ultimate. Teṣāṁ satata-yuktānāṁ bhajatāṁ prīti-pūrvakaṁ dadāmi (BG 10.10). Prīti-pūrvakam. This is very great determination, that "Kṛṣṇa, I simply want You, nothing, anything else. Nothing."
Na dhanaṁ na janaṁ na sundarīṁ kavitāṁ vā jagadīśa (Cc. Antya 20.29, Śikṣāṣṭaka 4). This is Caitanya Mahāprabhu's teaching. Caitanya Mahāprabhu has taught this philosophy repeatedly. Niṣkiñcanasya bhagavad-bhajana. Bhagavad-bhajana means He Himself become niṣkiñcana. He was Kṛṣṇa Himself, most opulent. Tyaktvā surepsitaḥ, sudustyaja-surepsita-rājya-lakṣmīm (SB 11.5.34). Caitanya Mahāprabhu had the most beautiful wife, goddess of fortune, Viṣṇu-priyā, Lakṣmī-priyā. But for the benefit of the whole world, although He is Kṛṣṇa, He showed us the example. At the age of twenty-four years, He took sannyāsa. He was not unhappy in His home. He had His very affectionate mother and... (aside:) Some fly... Affectionate mother and most affectionate wife, beloved wife. But still, it is very difficult to renounce the affection of mother and love of wife. But Caitanya Mahāprabhu did it. (aside:) The fly is still disturbing. So tyaktvā sudustyaja. Therefore in the Bhāgavata it is said, sudustyaja, very difficult to give up. Tyaktvā sudustyaja-surepsita-rājya-lakṣmīm (SB 11.5.34). And rājya-lakṣmīm, such nice beautiful wife, desired even by the demigods. Such a nice wife, He gave up.
