I just want to say that I’ve had several experiences with botanical n,n-dimethyltryptamine (which is also a hormone produced in a gland situated near the 3rd eye) that gave me quite typical colorful, radiant visions, and other perceptual changes.
When using a certain amount of plant matter, there are not so pronounced visions with closed eyes, but with open eyes the perceptual changes are very clear, and the general atmosphere is very similar to the cosmic experience described by Yogananda. I’m not talking about a few similarities here and there–many detailed similarities, as to the quality of the vision, the actual visual make-up, and what happens in Yogananda’s mind.
When using a bit more plant matter, what I experienced is very much like the Bardo Thodol as described in the Tibetan Book of the Dead. As vivid as 3D reality, I’ve seen entities as described in this book, and I was communicating with them without speaking. They are made out of light, and react to everything that goes on in my mind. E.g, within less than a second angels and buddhas become demons and monsters the moment my mind starts to slip into even a bit of fear and anxiety.
Illusion or not, plant-assisted or not, most of my experiences with this plant and other psychedelic plants have been neutral to fruitful. I’m happy when I haven’t used these plants for years, and I’m happy when there happens to be a month when I use it 2 times. I am typically humble towards psychedelic plants, and I am grateful they exist.
I like to do introspection, pranayama, and meditation before deciding to use a plant. I also like to first shake hands with the plant, in the form of taking only a small dose. Usually it feels ok to continue, but sometimes it feels like it’s not the right moment, so I leave it at that.
I have never taken a big dose of a plant I hadn’t used before. Every plant I use, I build up the dose very slowly and carefully, after informing myself as much as possible through literature of all disciplines. Especially psychopharmacology and ethnobotany are good sources.
For me psychedelic plants work well in conjunction with having an organic sugarfree msg-free vegan, ahimsa lifestyle with a lot of raw food, fruits, salads, etc. Short-term preparation for taking psychedelic plants can also involve fasting (2 hours up to a few days before ingestion). Doing asanas can also have immense influence. I think it’s highly recommendable to experiment with asanas and pranayama at some point shortly before ingestion, or during the experience.
I’ve also had several psychedelic experiences without using plants, for example through very specific pranayama (15 to 30 minutes of strong fast breathing through the nose–don’t try this at home without experienced guidance). These experiences are for me not less or more valuable than those with plants, nor are the things learned of completely different quality.
