The danger of LSD lies not in its toxicity, but rather in the unpredictability of its psychic effects. - Albert Hofmann

It's very, very dangerous to lose contact with living nature.

It could become of fundamental importance, and be not merely a transient fashion of the present, if more and more people today would make a daily habit of devoting an hour, or at least a few minutes, to meditation. As a result of the meditative penetration and broadening of the natural-scientific world view, a new, deepened reality consciousness would have to evolve, which would increasingly become the property of all humankind. This could become the basis of a new religiosity, which would not be based on belief in the dogmas of various religions, but rather on perception through the "spirit of truth." What is meant here is a perception, a reading and understanding of the text at first hand, "out of the book that God's finger has written" (Paracelsus), out of the creation. The transformation of the objective world view into a deepened and thereby religious reality consciousness can be accomplished gradually, by continuing practice of meditation. It can also come about, however, as a sudden enlightenment; a visionary experience. It is then particularly profound, blessed, and meaningful. Such a mystical experience may nevertheless "not be induced even by decade-long meditation," as Balthasar Staehelin writes. Also, it does not happen to everyone, although the capacity for mystical experience belongs to the essence of human spirituality.

el espacio interior del alma es igual de infinito y enigmático que el espacio cósmico exterior, y (...) tanto los cosmonautas del espacio exterior cuanto los del interior no pueden permanecer allí, sino que tienen que regresar a la tierra, a la conciencia cotidiana. además, ambos viajes exigen una buena preparación, para que puedan desarrollarse con un mínimo de peligro y convertirse en una empresa realmente enriquecedora.
