Man is deep down divine in essence. In order to reach union with the Transcendent Divine or the Cosmic Divine in life, he has to get over the dead layers of the entire race memory as found in him. The more developed the individual is, the greater are the endowments of mind. The endowments and faculties do not function as such, but start collecting below the surface fixed channels of habit. Habit formation is a dead layer of the inner human being and there are more organised versions of it.
Temperament is emotional habit.
It is basic for Yoga that one cannot reach the Divine through habits, however exalted they are in other fields. Man's relationship with the Divine is so transient that a few glowing moments appear in his life when he has glimpses of the Divine either as joy or elevation or luck or success. Later he returns to his human shell. Almost everyone gets such periods in his life. It is as though Man is born and lives a long life so that the possibility of these few moments will arise in his life.
