What is austerity? It is self-discipline. If one cannot sit for five minutes, how can you say, ‘I am disciplined’? There are people who cannot even sit still for five minutes, they are continuously moving. Their senses are active, their bodies are active, their pranas are active, their mind is active. There is no discipline. If there is discipline, if there is sanyam, consciously and wilfully, we can stop everything, including the chatter of the mind and the expression of negatives in life, and we can connect with the positive. Tapas means self-discipline – total and complete, in every respect.
