Below is footage from the 1950’s of the effects that LSD has on a seemingly ‘normal’ young woman. Watching it and hearing her words she seems to be describing a very intense spiritual experience. Her sense perceptions are heightened as she talks of seeing every molecule, she is immersed in a feeling of oneness with everything including the interviewer, duality no longer makes sense to her as she was asked if the experience was pleasant or unpleasant and couldn’t respond. Please watch as it makes for very interesting viewing.
After seeing that I recalled a video with Eckhart Tolle where he compares the use of acid with being fully immersed in the now. Check that out below (I have started the link where he begins talking about acid):
Another interesting video on the topic is by Jason Silva from the Shots of Awe channel on YouTube. He compares psychedelic hallucination with imagination and that modern technology is basically how we manifest these imaginings into reality. Enjoy!
