The First Mukha Padma Vakya!

It was in 1972 when many devotees were about to go to Vrindavan. Many devotees landed in Mathura and they took horsecart and went to Radha Damodar Temple as Srila Prabhupāda was staying there. After settling down they went to meet Srila Prabhupāda, Prabhupada was sitting on an asan. As there were only 10 devotees, they got the exclusive time of Srila Prabhupada. All were sitting in front of Prabhupada and Gurumaharaj too sat in front of Prabhupada. Prabhupada was delivering a lecture and Gurumaharaj was looking at everyone and then was looking at himself, this went on several times

Srila Prabhupāda was noticing his actions which made Srila Gurumaharaj think that he is getting special attention from Prabhupāda. 

As he was doing so a roaring voice came "Stop it!", Hearing which Gurumaharaj understood what he was doing.

When he used to listen to any lecture intensely he used to shake his thigh. 

 Guru Maharaj in many lectures mentions “that was the first instruction of Srila Prabhupada to me – Stop that! Since then, no matter how intense I’m while listening to the lecture I don’t shake my thigh except the time when I tell this pastime to everyone because I show them how I used to do”
