Even Krishna Himself thinks that he is imperfect to understand Radharani's feelings of devotion; and to understand the devotional feelings of Radharani, He became Lord Caitanya, to worship Krishna in the feelings of Radharani. So transcendental activities are so nice that it is all perfection, and still there is no perfect satisfaction. That is the duty of spiritual life.
