GIAN (Sanskritjnana), knowledge, understanding or consciousness; is what differentiates human beings from the animal world and establishes the superiority of homo sapiens over the other species. Nature has not only provided man with a qualitatively superior brain but has also endowed human mind with a dynamic inner stimulus called jagiasa (Sanskrit jijnasa), desire to know, inquisitiveness. Perhaps it is on account of this urge for knowledge and the consequent exercise that human brain or mind (psyche or soul for the ancients) gradually developed over the millennia.
