There's a lot of mention about finding "universal truths" and such In buddhism. That is how I feel , felt while on psychedelics. Observing things and understanding unspoken truths. It's not always so philosophic in nature and often times it's something that is already universally known anyways, like say "life is love". But while you're tripping there's a sense of profound understanding that love great, as you could say feel it radiating all around you, there's an "ah ha" moment that happens that is unique to you, if that makes sense. Of course the setting you're in and people you're hanging with makes a huge difference. I never had any deep thoughts whenever I would dropped acid at raves, I suppose it's due to sensory over load. But, the last time I did mescaline(I'm not 100% that was it but it was some psyechelic in powder form) me and my friends were practicing martial arts, and I had a zen moment. I was staring a fire, watching it breath and it seemed like I just understood the nature of all things. It occurred to me that such an element had no hatred, after all fire burns anyone just the same. I began to imagine my being to be as such, but the fire was too overwhelming so I moved on...... to water... I was staring at a glass of water, and the same thought occurred. Water does not judge or hate, it just is. Pretty soon I began to imagine my consciousness to be like water(Bruce Lee's famous words come to mind), still, stagnant, calm. I was at peace. At times I would poke at the water and see the ripple effects, I started to correlated that with my being again. A calm and steady state disrupted by ripples. Actions, reactions. The ripples soon became a way for me to understand exterior forces that disrupt my calm and steady body of water. Both external and internal factors could effect this calmness in me. I was to detach from them, and remain balanced, calm and steady should be my baseline. My mind was open in such a way that night in an everlasting way that my I look at things in a certain philosophical way that I've moved towards quit drinking, mostly solved my anger issues(with help of martial arts), and truly feel I have spiritually matured.
