Entheogens are not to be lightly trifled with... However, if taken with the right attitude and in the proper setting, psychoactive drugs may produce religious experiences. ...it is far less clear that they can produce religious lives.
Huston SmithSeen through the eyes of faith, religion's future is secure. As long as there are human beings, there will be religion for the sufficient reason that the self is a theomorphic creature - one whose morphe (form) is theos - God encased within it. Having been created in the imago Dei, the image God, all human beings have a God-shaped vacuum built into their hearts. Since nature abhors a vacuum, people keep trying to fill the one inside them.
Huston SmithI don't want to justify religion in terms of its benefits to us. I believe that, on balance, it does a lot of bad things, too - a tremendous amount. But I don't think that the final justification of religion is the good it does for people. I think the final justification is that it's true, and truth takes priority over consequences. Religion helps us deal with what is most important to the human spirit: values, meaning, purpose, and quality.
Huston SmithWe are free when we are not the slave of our impulses, but rather their master. Taking inward distance, we thus become the authors of our own dramas rather than characters in them.
