All About Bharatiya Sanatana Dharmam otherwise known as Hinduism : Ch-3.10.
CHAPTER- 3 : HINDU DHARMA-10.
Purity comprises both external purity and internal purity. Purity implies both purity of body and purity of mind. Purity of body is only the preliminary to purity of mind.
This body is the temple of God. It should be kept clean by daily bathing and clean dress. Cleanliness is a part of godliness.
The restriction in diet is best calculated to make the mind pure. Food exercises a direct influence on the mind.
Sattvic food makes the mind pure. Purity of food leads to purity of mind. Mind is only made up of the fine essence of food. As the food is, so is the mind.
You must be pure in thought, word and deed. Your heart must be as pure as crystal or the Himalayan snow. Then only the divine light will descend. Purity comprises such virtues as frankness, innocence, straightforwardness and absence of all evil thoughts. He who is endowed with purity will find it easy to tread the spiritual path.
