I stopped that practice bc it took me too much out of the world. At that time, I met a group that practiced dzochen and we met for sky gazing practice....which was a blast. And also practiced life as a meditation.
I'm currently doing a yoga asana practice that fulfills the meditation needs and is efficient bc it hits physical, emotional and spiritual needs. Also trying to organize a group to go sky gazing so hope to resume that in the New Year.
I think Alan Wallace also has a video on physics and meditation... Ill look for that. 🙏
