If you have love, you don't need to have anything else, and if you don't have it, it doesn't matter much what else you have. 
--Sir James M. Barrie-- 

Hatred paralyzes life; love releases it. Hatred confuses life; love harmonizes it. Hatred darkens life; love illuminizes it

Immature love says, 'I love you because I need you.' Mature love says, 'I need you because I love you.' 
--Erich Fromm-- 

Sleeping alone, except under doctor's orders, does much harm. Children will tell you how lonely it is sleeping alone. If possible, you should always sleep with someone you love. You both recharge your mutual batteries free of charge.

To the world you might be one person, but to one person you might be the world

You come to love not by finding the perfect person, but by seeing an imperfect person perfectly. 
--Sam Keen-- 

An act of love that fails is just as much a part of the divine life as an act of love that succeeds, for love is measured by fullness, not by reception 
--Harold Loukes--

One word frees us of all the weight and pain of life: that word is love. 
--Sophocles-- 

A relationship is like a rose, How long it lasts, no one knows; Love can erase an awful past, Love can be yours, you'll see at last; To feel that love, it makes you sigh, To have it leave, you'd rather die; You hope you've found that special rose, 'Cause you love and care for the one you chose. 
--Rob Cella-- 

Love is a gift of one's inner most soul to another so both can be whole 
--Tea Rose-- 

Love has its own time, its own season, and its own reasons from coming and going. You cannot bribe it or coerce it or reason it into staying. You can only embrace it when it arrives and give it away when it comes to you. 
--Kent Nerburn-- 

Give love and unconditional acceptance to those you encounter, and notice what happens. 
--Dr. Wayne W. Dyer-- 

To love is to admire with the heart; to admire is to love with the mind. 
--Theophile Gantier-- 

Love is eternal -- the aspect may change, but not the essence. There is the same difference in a person before and after he is in love as there is in an unlighted lamp and one that is burning. The lamp was there and was a good lamp, but now it is shedding light too, and that is its real function. And love makes one calmer about many things, and that way, one is more fit for one's work. 
--Vincent Van Gogh (1853-1890)-- 

How bold one gets when one is sure of being loved 
--Sigmund Freud-- 

 The best way to love is to love like you have never been hurt 
--Anonymous--

We live by admiration, hope and love. 
--William Wordsworth Alexandra Stoddard's Book of Days by Alexandra Stoddard 

We can only learn to love by loving. 
--Iris Murdoch-- 

Love is the immortal flow of energy that nourishes, extends and preserves. Its eternal goal is life. 
--Smiley Blanton-- 

Love is an energy - it can neither be created nor destroyed. It just is and always will be, giving meaning to life and direction to goodness...Love will never die 
--Bryce Courtney-- 

Love has nothing to do with what you are expecting to get - only with what you are expecting to give - which is everything. 
--Katherine Hepburn-- 

You will find as you look back upon your life that the moments when you have really lived are the moments when you have done things in the spirit 
of love. 
--Henry Drummond, British Clergyman-- 

There is no difficulty that enough love will not conquer, no disease that enough love will not heal, no door that enough love will not bridge, no wall that enough love will not throw down, no sin that enough love will not redeem... It makes no difference how deeply seated may be the trouble, how hopeless the outlook, how muddled the tangle, how great the mistake. A sufficient realization of love will dissolve it all. If only you could love enough, you could be the happiest and most powerful being in the world... 
--Emmet Fox--
