A disciplined mind leads to happiness, and an undisciplined mind leads to suffering.

Most folks are as happy as they make up their minds to be.

Happiness depends more upon the internal frame of a person's own mind than on the externals in the world.

Material progress and a higher standard of living bring us greater comfort and health, but do not lead to a transformation of the mind, which is the only thing capable of providing lasting peace. Profound happiness, unlike fleeting pleasures, is spiritual in nature. It depends on the happiness of others and it is based on love and affection.

There are two kinds of happiness - the temporary pleasure derived primarily from material comfort alone and another more enduring comfort that results from the thorough transformation and development of the mind.

We don't need more money, we don't need greater success or fame, we don't need the perfect body or even the perfect mate. Right now, at this very moment, we have a mind, which is all the basic equipment we need to achieve complete happiness.
