Premanand Maharaj Ji
Whom should I feel grateful to when someone helps me?
See Bhagwan in the helper
See the helper as Bhagwan working through a person, so your gratitude goes straight to Bhagwan. Gratitude does not mean putting up with wrong conduct.
So our gratitude goes straight to Bhagwan, not to the person. Because a person is one thing now and may be something else later.
