Prabhupāda: In the present condition, we do not know how Kṛṣṇa will be pleased, but we know from the śāstras . . . we can know also from the direction of the spiritual master how Kṛṣṇa will be pleased. Yasya prasādād bhagavat-prasādaḥ. So Viśvanātha Cakravartī Ṭhākura says you have to follow the direction of the spiritual master. He's guiding as a leader. And if he's pleased, that means Kṛṣṇa is pleased. Yasya prasādād bhagavat-prasādaḥ.
The devotional service is the only way. Karmī, karmī means they are working very hard for their personal benefit, not for Kṛṣṇa's benefit. Similarly, jñānīs, they are also trying for personal benefit, mukti. He wants mukti, liberation, nirbheda-brahmānu-sandhana. And similarly, yogīs also, they want personal benefit, some material power, aṣṭa-siddhi-yoga, aṇimā-laghimā-siddhi.
Bhukti-mukti-siddhi-kāmī sakali aśānta (CC Madhya 19.149). Caitanya-caritāmṛta kar says except pure devotee, who only wants to satisfy Kṛṣṇa, everyone is working for his personal benefit, karmī, jñānī, yogī. But Kṛṣṇa says: "Pure devotional service . . ." Not . . . Rūpa Gosvāmī says: "Pure devotional service is the only means to attract Kṛṣṇa." Hmm. Now . . . but ignorance is no excuse.
Go on reading. Next. "Generally, one commits sinful activities . . ."
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.
