Shuddha upayog (applied awareness of the Self, The Soul) means to be able to see the Soul and the Body of the other person as separate. The constant contemplation of ‘I am pure Soul (Shuddhatma)’ is shukladhyan (pure contemplation as the Self). - Dada Bhagwan
Who is doing this? Who am I? What is all this? Who is the doer? Who is the nimit (instrumental doer) of this? If all these remain present ‘at a time’ exactly the way it is, then that is considered shuddha upayog (pure focused applied awareness of the Self, the Soul). - Dada Bhagwan
