The cycle of time.
One kalpa or cycle of time from creation to dissolution (day of Brahma), lasts 4.3 million years. These cycles continue on for the life of Brahma (100 years of 360 Brahma days and nights). The process then, with variations, repeats itself.
Hinduism > Brahma Rishi
Summarizing the state of consciousness of the mind-born sons of Brahma.
Brahma is the name for the principle which creates all of the manifest realms.
Brahma is a metaphor for all of creation: its laws, its inherent intelligence, and its consciously manifested potencies which operate as sages, saints, Rishis, Devas, celestials, and divine beings of all kinds of nature, temperament and description.
Brahma creates, operates in the form of this universe for trillions of years, then dissolves back into Narayana. Later, another Brahma appears to begin the process again.

The basic castes in Caste System. Also called "colours".
The pattern of social classes in Hinduism.
Vedic scriptures speak of the idea that a person must be recognized as a caste to be a member. A worker could become qualified and become a priest.
However, the idea of Karma is such that a person may have become qualified to increase in caste because of past actions.
