Premanand Maharaj Ji
What is the difference between balihari and dhanyavad, and should I thank my Guru?
The Guru bond has no thank-you in it
Thanks and gratitude are for others, but the Guru is your own soul, so say balihari, not dhanyavad. Do not mix thank-you into the Guru bond, the purest relationship.
Thanks or gratitude is offered to others. The Guru is our own soul. Just as we cannot express gratitude to our own mother, we cannot to the Guru.
