Meditation has changed me profoundly as well. I started with 2 minutes and now I do at least 1 hour everyday. It actually all started with weed. From there to yoga, then meditation, then shrooms and finally spirituality and Nondualism. I not in control of anything anymore; that delusion has gone away. This journey of self discovery is turning out to be the greatest adventure of my life.
I can't even recognise the person I was 4 years ago. I've left that person far behind.
