In 1996 during Rathyatra time, Srila Gurudeva was advised by the Doctors not to bend much and to avoid movements (dance and kirtans) due to injury to His back. That time in Agartala I personally saw Srila Guru Maharaj would bend down to do full dandavat pranams (prostrated obeisance) to the Supreme Lord with great difficulty.
When objected to do this he would say if pranams were not done before the Supreme Lord then feeling of pride will remain in the mind. Morning and evening after arati parikrama he would offer pranams to all Vaishnavas along with others. Also, He could not stop himself from performing dance and kirtan before Rath.
