Pure devotion to Krishna instantly dissolves all sin like sunlight dispelling fog, requiring only sincere determination.Listen — Srila Prabhupada Uvaca
Prabhupāda: Oṁ namo bhagavate vāsudevāya. Oṁ namo bhagavate vāsudevāya. Oṁ namo bhagavate vāsudevāya. [devotees repeat] Śrīmad-Bhāgavatam, Canto Six, Chapter One, verse number fifteen.
[02:04] kecit kevalayā bhaktyā vāsudeva-parāyaṇāḥ aghaṁ dhunvanti kārtsnyena nīhāram iva bhāskaraḥ [SB 6.1.15] So karma, jñāna, yoga, then bhakti. So karmaṇā, karma nirhāro na hy ātyantika iṣyate. [SB 6.1.11] We have discussed this. By karma you cannot nullify something...
Jñāna also, theoretical. It has been seen that theoretical knowledge, even one has come to the platform of Brahman... Āruhya kṛcchreṇa paraṁ padaṁ tataḥ patanty adho [SB 10.2.32]. There are many examples. Simply theoretical knowledge will not help us.
Our main aim is how to become perfect. So by karma we cannot become perfect perpetually. Just like I have given several times the example that in spite of so much education and universities and advancement of civili..., nobody is perfect in the modern civilization, not even honest. In spite of education, so much learning... I have given this example many times.
This is tested in the airport, that everyone is examined about his dishonest. That means nobody is honest. So this will not help. If you want to make the world perfect, then not by karma, neither by mental speculation.
That is not possible. The only means is bhakti, especially in this age. In this Kali-yuga people are very much embarrassed. Mandāḥ sumanda-matayo manda-bhāgyā hy upadrutāḥ [SB 1.1.10].
Manda-bhāgyā. Even nobody is happy in his family life, so unfortunate, manda-bhāgyā. That is practical. So these things will not help, especially in this age. So Śukadeva Gosvāmī suggests for kecit, "somebody," not all.
