RENUNCIATION means the giving up of the style of living dominated by worldly ambition and craving and discarding the love of possessions for the sake of achieving the ultimate goal of religious life. The theistic traditions hold that when one is united with God, all else loses its significance. In this sense, God realization can be viewed as the culmination of renunciation. A devotee of God is supposed to withdraw from the world to practise piety in loneliness, and to resort to self denial, so that he can see and know and be one with God.
GIAN (Skt.jnana), 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 (Skt. 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 millenia.
