This is the symptom of a pure devotee. One should serve the spiritual master first. It is not that one should bypass the spiritual master and desire to serve the Supreme Lord.This is not the Principle for a Vaishnava. — Srimad Bhagavatam, 07.09.28.
The spirit soul is ever fresh. He is always different from the material body & mind is always subject to disturbances.
Surrender fully unto the lotus feet of the Lord. That is the only business of the perfect human being.
Srimad Bhagavatam 1.5.20,
