Answer: Knowing and loving are the obverse and the reverse of the same coin. At first we may not be able to love the Lord, but we can be impressed by His majesty through the manifestation of it through Nature that forms our external environment. This is a kind of partial knowledge. But if it is real, intense and a result of real quest, it can develop the emotion of awe, not fear as on seeing a tiger. The more we study Nature, the more are we impressed by the wisdom that is revealed through it. In the course of our development, it can lead us to love for Him. Bhakti is described as firm and unshakable love, preceded by an understanding of Dive Majesty. It is vastly different from personal love with other human being.
