My mind has become purified because I have associated with Advaita Acarya, who is directly the Supreme Personality of Godhead.

He is unparalleled in His understanding of all the revealed scriptures and the devotional service of Lord Krsna. Therefore He is called Advaita Acarya.

He is such a great personality that by His mercy He can convert even the meat-eaters [mlecchas] to the devotional service of Krsna. Who, therefore, can estimate the power of His Vaisnavism?
