Quotes on Karma:

I am the owner of my karma.
I inherit my karma.
I am born of my karma.
I am related to my karma.
I live supported by my karma.
Whatever karma I create, whether good or evil, that I shall inherit.

It is believed that if we ignore the workings of karma, we are creating problems for ourselves as “knowledge on Karma” can actually help us improve ourselves, our lives. Thus, we cannot blame our destiny for it is a known fact that “you are the result of your own deeds” as explained in the quote below:

Watch your thoughts, for they become words.
Watch your words, for they become actions.
Watch your actions, for they become habits.
Watch your habits, for they become character.
Watch your character, for it becomes your destiny.

Buddhist point of view on Karma:

Buddha said:

“Do not think a small sin will not return in your future lives.
Just as falling drops of water will fill a large container,
The little sins that steadfast accumulate will completely overwhelm you.

Do not think a small virtue will not return in your future lives.
Just as falling drops of water will fill a large container,
The little virtues that steadfast accumulate will completely overwhelm you.”
