Whatever you do for your own satisfaction, for the satisfaction of your whims, that is mahā-pāpa, great sin. The same thing, when you do for Kṛṣṇa, that is opening your path to liberation, back to home, back to Godhead. This is difference. You have to change the consciousness. What you are doing? For whom you are doing? For yourself or for Kṛṣṇa? This is Kṛṣṇa consciousness. And that is the perfection of life. In whatever position you are, whatever you are doing, it doesn't matter. That is confirmed in the Śrīmad-Bhāgavatam,
- ataḥ pumbhir dvija-śreṣṭha
- varṇāśrama-vibhāgaśaḥ
- svanuṣṭhitasya dharmasya
- saṁsiddhiṁ hari-toṣaṇam
- (SB 1.2.13)
Hari-toṣaṇam means to satisfy the Supreme Lord, Hari. That is perfection. It doesn't matter what you are doing. Varṇāśrama-vibhāgaśaḥ. First of all, "whatever doing," it does not mean whatever nonsense you are doing, that will be accepted. No. Varṇāśrama-vibhāgaśaḥ.
