When Krishna is pleased by our activities then He will give us that pleasure. That is the superior form of pleasure, that is the pleasure that is the sustainable pleasure, which will enable the devotee
to continue in the face of all obstacles to execute his duties as desired by the Lord. When one comes to the spiritual platform, which is called Brahma-saukhyam (spiritual happiness), which
is achieved by austerities and penances one can achieve the divine position of devotional service.
