In plain words
Where they all arrive is the ocean. The learning of the Self is like the sea. The ocean alone is the goal of all rivers. However much learning you acquire, in the end you cannot escape joining the ocean called grace. With that faith, and with effort of that kind, develop this principle of Prema. We must not find fault with nature at all. We cannot give up nature at all. This too is a form of God. This Prakṛti is the form of the effect. The Paramātma is the cause. The world is the relation of cause and effect. You must see divinity in that too. You can perceive divinity in every atom. So we must not bring our life to its end with worldly learning alone.
