You must avoid at least sinful activities.
- yeṣāṁ tv anta-gataṁ pāpaṁ
- janānāṁ punya-karmaṇām
- te dvandva-moha-nirmuktā
- bhajante māṁ dṛdha-vratāḥ
- (BG 7.28)
You cannot become a devotee unless you are completely sinless. So to become completely sinless you have to begin with these four prohibitory injunctions, or avoid sinful activities like illicit sex, meat-eating, smoking, intoxication and gambling. Then you'll be gradually completely sinless. One side, to practice things, and another side, to engage yourself in devotional service. To engage oneself devotional service under the order of spiritual master and the śāstra means to remain on the transcendental platform. Transcendental platform means there is no sinful activity. It is above. Sinful . . . Pious and sinful activities are there so long you are on the material platform. Good and bad. Piety and sinful. But when you are on the transcendental platform, then you are automatically without sin.
- māṁ ca yo 'vyabhicārena
- bhakti-yogena yaḥ sevate
- sa guṇān samatītyaitān
- brahma-bhūyāya kalpate
- (BG 14.26)
Sin . . . life of vice and life of piety, they are within this material world. But when one is spiritually engaged, he is above the spiritual plane.
