From Nectar of Devotion

In the Skanda Purāṇa there is a statement by devotees praying to the Lord: "My Lord, I know that young girls have natural affection for young boys, and that young boys have natural affection for young girls. I am praying at Your lotus feet that my mind may become attracted unto You in the same spontaneous way." The example is very appropriate. When a young boy or girl sees a member of the opposite sex there is a natural attraction, without the need for any introduction. Without any training there is a natural attraction due to the sex impulse. This is a material example, but the devotee is praying that he may develop a similar spontaneous attachment for the Supreme Lord, free from any desire for profit and without any other cause. This natural attraction for the Lord is the perfectional stage of self-realization.
