In the nectar of instruction Srila Rupa Goswami text (2) said

than we need to be very careful when we practice Krsna

conciousness, he said( prajalpo nijamagrahah)  practicing

the scriptural rules and regulation only for the sake of

follow them and not for the sake spiritual advancement.

Than means we follow are rules and regulation for love Guru,

krsna and the devotees and not for our sense gratification

subtle or gross. We practice with humble feelings, Iam nothing

only the servant of the servant of my guru. !HARE kRSNA!
