Reverse osmosis or water distillation are two methods to counteract this, with water distillation being the less expensive choice.
We are really concerned about the gap between our spirituality and reality, not to be accused of being conspiracy theorists. According to Rick Strassman, M. D., DMT and the pineal gland are closely related:
We all have DMT in our body, which is why I was attracted to it. I thought the enigmatic pineal gland, a little organ located in the middle of our brains, was the source of this DMT.
The function of this gland has a long philosophical history, but modern medicine understands very little about it.
For instance, both Western and Eastern mystical traditions situate our ultimate spiritual center inside the pineal, which Descartes considered to be the “seat of the soul.”
