The ultimate result of devotional service is to develop genuine love for the Supreme Personality. Love is a word which is strictly used in relation with men and woman. That is the etymological order in the English language. And therefore love is the only word that can be properly used in relation with Lord Krishna and the living entities. The living entities are mentioned as Prakriti in the Bhagwat Geeta and in Sanskrit. Prakriti is a feminine object. The Lord is always described as the Parama Purusa or the Supreme Male Personality. As such the affection between the Lord and the living entities are of exactly like the male and female. Therefore the word Love of Godhead by the living entities is quite appropriate.
