I think enlightenment can be a tricky word to talk about, but I certainly think people carry with them various levels of positive energy, consciousness and knowledge of the path in different forms and expressions. Everyone is learning, and this world/universe is here to teach you about it and push one to grow regardless of work with DMT or not. I think you got it when you said DMT accelerated your growth. It is a catalyst, but one still needs to walk the path. If one has been walking and learning from the path for a while, then no catalyst is needed. It's like, all the materials are there.. the paint has always been there, it just depends if you have an art teacher or not as to how quick you learn. Either way, it requires practice and error.
Answering your question more.. I have met people absolutely on 'my level' who have never touched a substance. I actually am currently attending a Christian institution where I sometimes meet people who carry immense amounts of light and positivity that is beyond even what I can bring sometimes. And I too wonder.. how the heck did they get there? Have they met the other side and the entities? And they usually haven't, but they've come to understand some of the truths and paths of this universe via other means - whether religion, study, or various forms of charity. Regardless of the path taken, learning seems to occur. DMT is a teacher and tool, but certainly one can be an autodidact.
