The three kinds of love

What are the three kinds of love according to a Saint?

Saint Paisios the Athonite: For me there are three kinds of love: that of the flesh, which is full of spiritual germs; secular love, which is superficial, formal, hypocritical and without depth; and spiritual love, which is true, pure and precious love. This is love which can continue ‘unto the ages of ages’.

-How will I know that I have real love, Elder.

Saint Paisios the Athonite: In order to understand, see if you love all people equally and whether you think all of them are better than you.
