WHAT DOES ‘GURU’ MEAN?
GURU means “gu’ actually means darkness while “ru” means light. The two serve as a principle for the development of consciousness where it leads the creation from unreality to reality, from the darkness of ignorance to the light of knowledge. – from ‘UNIVERSAL TRUTH: thinking outside the box’ by Peter C Rogers D.D., PhD
The term Guru is therefore explained as the remover of darkness, who reveals the light of the heart.
