Definitely. Psychedelics are useful in showing us the possibilities of the mind, especially for those of us who might have had a restricted outlook on what mind is capable of due to a secular worldview. But once we open that door, the correct way to open the door again and enter is with the right keys. Psychedelics are sort of a battering ram in this context. To quote Alan Watts on psychedelics, "once you get the message hang up the phone," to which I add: hang up the phone or risk getting strangled by the cord.
