Energy work aka qigong when done correctly will actually induce more powerful altered states than most external substances, it is the same with some yogic practices.
If you go back far enough you’ll find that at one point both the vedic and daoist tradtions used specifically concocted and ritually empower blends of mind altering substances in specific rituals. But these practices faded as they developed energy practices that fulfilled the same role and induced similar or stronger states.
If ya need a starting place for basic energy work the video list i have posted in the thread below has some simple but powerful work in it.
