The servant of the guru has no other means except following in the footsteps

of Sriman Mahaprabhu and Prabhu Nityananda under the guidance of Sri Guru.

He is unable to act in accordance with the tastes and nature of the bound

jiva thereby disobeying the injunctions of the guru and of the scriptures.

This constitutes his proper function of honoring others. In such conduct

there is no deficiency of the quality of humility that is greater than that

of a blade of grass. This is the humble submission of the servant of the

servant of the guru.
