Question to Radhanath Swami: It is recommended that we fast on the birthdays (usually called the appearance days) of great acharyas or spiritual preceptors. Similarly, it is recommended that we fast on the anniversaries of their departure from this world (disappearance day.) What is the importance of this fasting?
Radhanath Swami: Ultimately, it’s to show our love and appreciation for what that great acharya or spiritual preceptor has done for the world. Performing tapasya or austerity is a way of showing love on the path of bhakti.
