It [the pleasure of sex] is the reason why the vital sex-difficulty is the hardest to get rid of – even those who have sincerely given up the more physical form are liable to the vital form of the impulse. But it is harmful because it allows a subtle infiltration of the forces that stand in the way of the sadhana. One must get rid of them if the vital is to become entirely pure and able to contain the divine love and Ananda.
