Austerity is often mistaken to be poverty, self-denial. It is neither. Austerity comes out of maturity. It is a sign of social health. Often people who practice austerity are resentful of richness. This is a very pitiable state. Such austerity is not born out of maturity but out of compulsion. The true austerity has tolerance for richness and is never resentful.
In fact, one who is mature will have pity for one who is not austere. Austerity is not against celebration and just vanity is not celebration. Celebration dawns in the spirit. Only one who is rich in spirit can practice austerity. One may be rich materially but if he is poor in spirit he can neither celebrate nor evolve. Poverty of spirit is vanity. Austerity brings freedom from the pride of vanity. But taking pride in austerity is again a vanity!
Austerity comes out of abundance, and austerity brings abundance. If you feel a lack in any area of life, immediately start austerity. Austerity not only brings freedom but nurtures sharing and caring.
