Sahajyoga

It is a type of spontaneous yoga in which devotee does not thrive to achieve stage of meditation but let the stage of unfold itself to him, without help of human guru.

This is the way of attachment not detachment. You just need to attach holy mantra of "Hari Om Tatsat Jai Guru Datta" through your way of sadhna without changing your own religion, mantra and guru.
