Pradyumna: ". . . due to ignorance. But ignorance is no excuse for evading the reaction—sinful activities."
Prabhupāda: Yes. Generally we commit sinful activities knowingly; if not knowingly, unknowingly. Just like we are walking on the street, we are killing so many ants, unknowingly. So that is also sinful activities. You do not know, you do not want to kill the ants, but still, unknowingly, you are killing. When you take water from the jug, there are so many animals encircling the water jug, and when you take water some of them die. When we make paste on the pestle and mortar, spices, so many small insects die. That is going on.
So knowingly or unknowingly, we are committing sinful activities. So how to save? That is replied in the Bhagavad-gītā: yajñarthe karma anyatra loko 'yaṁ karma-bandhanaḥ (BG 3.9). If you do not act, or if you do not engage yourself in Kṛṣṇa consciousness business, then you are becoming implicated with so many sinful activities. That is sure.
Therefore one has to take to Kṛṣṇa consciousness without fail. Otherwise he'll be entangled, karma-bandhanaḥ. Even if he's doing pious activities, he's becoming entangled in karma-bandhanaḥ, in bondage. He has to take birth. Pious activities means he has to take birth in nice family, rich family. That is also bandhana. He has to enter into the womb of the mother and live there for ten months, in compact, airtight, compact bag. That is not very good living condition. But we forget all these things, neither we do not care for these things.
But actually, fact is, knowingly or unknowingly we are becoming implicated. But if we simply take to Kṛṣṇa consciousness and if we engage ourself in His unalloyed devotional service, if we try to understand Kṛṣṇa, His activities, His form, His name, His quality, His paraphernalia, then the result will be, as Kṛṣṇa says, tyaktvā dehaṁ punar janma naiti mām eti (BG 4.9). There is no question of reaction. Because Kṛṣṇa says . . . even we are doing . . . that we are bound to do, as I have already explained, that knowingly or unknowingly, we are committing sinful activities. But Kṛṣṇa gives His assurance: ahaṁ tvāṁ sarva-pāpebhyo mokṣayiṣyāmi (BG 18.66). So if he . . . of course, a devotee never does anything knowingly sinful, but unknowingly, he's doing. But Kṛṣṇa is taking charge of him. Ahaṁ tvāṁ sarva-pāpebhyo mokṣayiṣyāmi. So there . . . there is no question of grief.
Therefore the subject matter is relief from material distress. If you take to Kṛṣṇa consciousness without any motive, sincerely, then your position is secured. Kṛṣṇa takes charge of you. Kaunteya pratijānīhi na me bhaktaḥ praṇaśyati (BG 9.31). His devotee will never be vanquished. Just like Arjuna. Arjuna was considering how he could kill his kinsmen, his family men, his nephew, his brother, his grandfather, on the other side. Actually, this killing business is not very good. It is sinful. But the same thing he committed after understanding Bhagavad-gītā. He agreed, kariṣye vacanaṁ tava (BG 18.73): "Yes, I shall fight." So does it mean . . .? In the beginning he was considering about the sinful effects of his activities. Why did he engage himself in the same business, although he knew this is sinful? No.
