Today I found an interesting and cool quote about the happiness and peace:

To achieve that state of lasting happiness and absolute peace, we must first know how to calm the mind. By turning the mind’s concentration inwards, upon the self, we can deepen that experience of perfect concentration. This is the state of meditation.

– Swami Sivananda

Happiness is nothing but of living a good life, or flourishing a good life. But to achieve that state of lasting happiness and absolute peace, you must calm down yourself.
