Chanakya

There is no austerity equal to a balanced mind, and there is no happiness equal to contentment; there is no disease like covetousness, and no virtue like mercy.

The happiness and peace attained by those satisfied by the nectar of spiritual tranquillity is not attained by greedy persons restlessly moving here and there.

Never make friends with people who are above or below you in status. Such friendships will never give you any happiness.

As long as your body is healthy and under control and death is distant, try to save your soul; when death is immanent what can you do?

Before you start some work, always ask yourself three questions - Why am I doing it, What the results might be and Will I be successful. Only when you think deeply and find satisfactory answers to these questions, go ahead.

Once you start a working on something, don't be afraid of failure and don't abandon it. People who work sincerely are the happiest.
