Love is an efflux.   It is the outpouring of our very being into the being which is dear to us.   Yet we are not left impoverished, but enriched beyond the dreams of spiritual avarice. 

We must always be giving each other bread, or money, or jewels, or books, or counsel;  and then we think we have accomplished something.   But love is the real gift, no other can take its place;  but it can take the place of all the rest. 

Better to love than be beloved, 
Though lonely all the day;
Better the fountain in the heart
Than the fountain by the way.

Self is the only prison that ever binds the soul;
Love is the only angel who can bid the gates unroll:

Jealousy is impossible to love, for ‘love seeketh not its own’;  and jealousy is always selfishness.

For truly, nothing does so freeze affection, as the breath of jealousy.

Fellow Travellers.   
The friends thou hast, and their adoption tried, 
Grapple them to thy soul with hooks of steel.
