The actual chemical is different and the way you take it (orally, by nealing in front of a shaman and drinking about a shot glass of it) has an affect on the duration and intensity (like a lot of drugs).
You can smoke dmt purified or a yagi mix and have different more intense experiences but that might only be 30 minutes.
As for integrating your thoughts, I can definitely put that down to the chemical. It's called "abuelo" by the native people because it's like your grandfather giving you advice. Mushrooms are known as the "ninos" because they're a lower level in comparison.
Understanding the sacredity of plants and developing a respect for native medicine has been a great part of my experience in South America.
Have yet to have anyone indigenous try and sell me on this
There are also the "passing through want to try it" attendees.
However, given the power of this substance to have a positive effect on someone's life, I'm not going to build walls around it. Also, it's a very challenging experience and anyone that goes through it deserves a bit of respect.
