This is mainly from personal observations and after reading tons of material. The answers to all personal or self issues are deep within us and that can be bubbled up only through deep meditations. I remember when I was a kid, started reading books on yoga and meditation all by myself even though there was no one in my family doing it. I sometime reflect on why at that age felt the need to do meditation. The only reasoning is due to past life habits and inclination.

I meditated even though sometimes it gave me headaches but now i can easily sit 2-3 hours.
