If one cannot say that the spiritual master is the personal manifestation of the Supreme Personality of Godhead, one will not be able to utter the holy name of the Lord.
Of all worship, the worship of the Supreme Personality of Godhead is the greatest but the worship of the lotus feet of the spiritual master is even greater than the worship of the Supreme Personality of Godhead.
In this world of Maya, which is averse to the Lord, full of trials and tribulations, only patience, humility and respect for others are our friends for Hari bhajana.
Unless this is firmly realized we cannot understand what saintly association means, we cannot understand what the shelter of a spiritual master means, we cannot understand that we are dependent and he is our maintainer.
If we take shelter of the lotus feet of the spiritual master, we can become free from illusion, fear and distress. If we wholeheartedly beg for his mercy without any deceit then the spiritual master bestows all auspiciousness upon us.
By distributing the holy name of the Lord, he cleanses the hearts of the most fallen people. Therefore he extinguishes the blazing fire of the material world.
