Man is attuned to any one type of nature – Tamas, Rajas or Saatvic.
In earlier days, the nature of man decided which community he would belong to. A Shudra was one who sold his time. A Vaishya was one who sold a product or his creativity. A Kshatriya was one who sold his confidence and valour. A Brahman was one who sold his intelligence. Thus took root the Indian Community system.
Understand how to transcend all these virtues and rise beyond them to become one with the Supreme Self that is beyond all passivity, passion and purity.
