Śrīmad-Bhāgavatam 7.9.9
—
Māyāpur, March 1, 1977
Liberation means... We are entangled in this material world because we are creating one after another entanglement. Nūnaṁ pramattaḥ kurute vikarma [SB 5.5.4]. Because we are in such a position that we have to act obversely, not properly, even if you do not desire... Even if you are very careful not to kill even an ant, still, unperceptibly, imperceptibly, you, while walking, you kill so many ants. And don't think that you are not sinful for that purpose. You become sinful. Especially those who are nondevotees, they must be responsible for killing so many small creatures while walking or while... There is waterpot, you have seen. So many small animals are there. Even by moving the waterpot, you kill so many living entities. While igniting fire in the oven, there are so many living entities. You kill them. So consciously, unconsciously, we are in such a position in this material world that we have to commit sinful activities even if we are very, very careful. You have seen the Jains, they are after nonviolence. You'll find they keep a cloth like this so that the small insects may not enter the mouth. But these are artificial. You cannot check. In the air there are so many living entities. In the water there are so many living entities. We drink water. You cannot check it. It is not possible. But if you keep yourself fixed up in devotional service, then you are not bound.
Yajnārthe karmaṇo 'nyatra loko 'yaṁ karma-bandhanaḥ [Bg. 3.9]. If your life is dedicated for yajna, for serving Kṛṣṇa, then the inevitable sinful activities which we commit without any knowledge, we are not responsible. Manye mithe kṛtaṁ pāpaṁ puṇyaya eva kalpate (?). So our life should be dedicated simply for Kṛṣṇa consciousness. Then we are safe. Otherwise we must be entangled with so many reaction of our activities and bound up in the repetition of birth and death. Mām aprāpya nivartante mṛtyu-saṁsāra-vartmani [Bg. 9.3].
nūnaṁ pramattaḥ kurute vikarma
yad indriya-prītaya āpṛṇoti
na sādhu manye yato ātmano 'yam
asann api kleśada āsa dehaḥ
[SB 5.5.4]
The safest position is let us always be engaged in Kṛṣṇa consciousness. Then we make spiritually advance and safe from the reaction of sinful life.
