Chakras

Chakra - energy reception/perception center, which connects person with the external System (under System* we mean the external information, set of phenomena which surround a human being). Each person, according to own caste (level of System* perception), has a particular character of chakras' circling, that defines the quality of interaction with the world. It's worth mentioning that one may observe the number 7 set in other aspects of space functioning: seven notes; seven days in a week; spectrum of colors etc.
