Dada Bhagwan said this quote

In this life, you only need to do this much: You must know that the other person is instrument (nimit, in bringing you the results of your own karmas) so you must remain silent. Do not let the mind spoil in the slightest. If it does, then ask for forgiveness: ‘Dear Instrument! You are simply an instrument. I ask for forgiveness for spoiling my mind.’ You have to do only this much! That is the effort [purusharth]!
