Typically Ray Man Shabd is used during bound lotus, but it is not required. You can use any mantra you want during your BL practice, and it will amplify your experience with that mantra. Does anyone have any experience using different mantras? I just switched from Ray Man Shabd to So Purkh because that’s what spirit wanted…have been having internal conflicts about the male divine so I have been playing So Purkh now and I’m experiencing a lot of stuff coming to the surface and clearing. It hasn’t been a picnic but I’m glad it’s getting the work done. Love this meditation. There is no room for anything but truth in this posture.
