This is a great thread! I've always wondered what brought others to Buddhism.

For me, it was just more of a realization. I'd had all of these insights and 'weird' ideas about things (for example, doubting whether I exist or not, a feeling of losing my sense of separation from all the things around me, etc.) and a friend here in Japan said, 'That sounds like the Zen Buddhist experience.'

I started reading whatever I could get my hands on (Alan Watts, D.T. Suzuki) and started meditating regularly.

...and then I realized I had a long way to go still!
