The beginnings

As a first step, I got in touch with a preceptor, or a guru. He was not a 'Sadhu' or anything like that. He was just a simple software engineer, like me.... nice guy. He asked me to take 3 sittings with him, on 3 successive days. During the 3 sittings, he explained me the process/technique of meditation, and the philosophy behind it.
My experience was that, after each session, I felt very light-headed, fresh, and lively. This was a very new experience for me. I shared it with my preceptor. He mentioned that it was a good sign.
