If there is no chance of directly serving the spiritual master, then the devotee does serve him by remembering his instructions only. There is no difference between the spiritual master’s instructions and the spiritual master himself. In his absence, therefore, his words of direction shall be the guide of the disciple. If a man thinks that he is above all suspicion and therefore there is no need of consulting any other else including the spiritual master, he becomes at once an offender in the lotus feet of the Lord and an offender can never go back to home back to Godhead. It is imperative also that a seriously inclined person must accept a bonafide spiritual master in terms of the Shastric injunction and give up the company of a pseudo spiritual master in terms of social usages and hereditary or customary and ecclesiastic conventions.
