Karma

Since i was a young kid, I believe in Karma. Now i strongly believe in Karma. I saw many things to prove the existence of it.

Whats karma? Its the universal law that Buddha preached. Meaning Intentional Actions and this refers to what the buddhist belief in the Cause and Effect. In layman terms it can be explain:
A person who has done much good and accumulated alot of positive karma will enjoy a happy life and gravitate towards a Human, or even a Heavenly realm of existence in the next rebirth.
Conversely, someone who has done much bad deeds and accumulated much negative karma may have a life plagued with difficulties and then also be reborn in the Lower realm of existence.

The importance of Karma:
Karma is the only possession we really own and which we take with us from life to life.
Every intentional act of the body, speech and mind is like a seed planted that will grow when the conditions are right. Thus as you sow, you shall reap.
