What forms of yoga and meditation are best for bringing about the relaxing effects of marijuana without relying on external stimuli?
No form will work if seeker is looking for a replacement of Marijuana.
Marijuana is unconscious way and Yoga is conscious way. Marijuana is effortless and Yoga is with effort. Marijuana is to lose self and Yoga is to realize self.
There is no way that Yoga and meditation will replace the marijuana. if you really want to fix the issue of marijuana consumption try some rehab center where they will take care of your issue.
