The woods are lovely, dark and deep. But I have promises to keep, and miles to go before I sleep. Robert Frost
True love is not a strong, fiery, impetuous passion. It is, on the contrary, an element calm and deep. It looks beyond mere externals, and is attracted by qualities alone. It is wise and discriminating, and its devotion is real and abiding. Ellen G. White
Deep into that darkness peering, long I stood there, wondering, fearing, doubting, dreaming dreams no mortal ever dared to dream before. Edgar Allan Poe
As a single footstep will not make a path on the earth, so a single thought will not make a pathway in the mind. To make a deep physical path, we walk again and again. To make a deep mental path, we must think over and over the kind of thoughts we wish to dominate our lives. Henry David Thoreau
Unconditional love really exists in each of us. It is part of our deep inner being. It is not so much an active emotion as a state of being. It's not 'I love you' for this or that reason, not 'I love you if you love me.' It's love for no reason, love without an object. Ram Dass
