Is this something you came up with yourself? Or is it a well known meditation technique? Or derived from one? And for how long do you do this at a time?
Friend of mine did weekly classes, and labeled the classes as "Tantra", but the only interpersonal interaction was a ~5m eye gaze with the teacher sometime during ~1-2 hour class. So I don't have any clue what terms to use to find it on the 'net.
