Unity is love. It cannot be established without love. Therefore try, as far as possible, to be filled with love. Love is perpetual life, the most perfect vitality. Consider how love has gathered us together from the East and the West! If there were no love between us our friendship would have been concluded with salutations, such as “Good morning” and "Good evening." Love draws us in friendship to the people of every race and religion. He is a Baha’i, of the people of Baha, from whom we breathe the fragrance of this love again. …
The highest love is independent of any personal advantages which we may draw from the love of the friend. If you love truly, your love for your friend will continue, even if he treats you ill. A man who really loves God, will love Him whether he be ill, or sad, or unfortunate. He does not love God because He has created him -- his life may be full of disassociations and miseries. He does not love God because He has given him health or wealth, because these may disappear at any moment. He does not love Him because He has given him the strength of youth, because old age will surely come upon him. The reason for his love is not because he is grateful for certain mercies and benefits. No! The lover of God desires and adores Him because He is perfection and because of His perfections. Love should be the very essence of love, and not dependent on outward manifestations.
A moth loves the light, though his wings are burnt. Though his wings are singed, he throws himself against the flame. He does not love the light because it has conferred some benefit upon him. Therefore he hovers round the light, though he sacrifices his wings.
This is the highest degree of love. Without this abandonment, this ecstasy love is imperfect.
The lover of God loves Him for Himself, not for his own sake.
