The dominant energy hitting Half Moon Bay is from a combination of swells which together, beyond ideas of wrongdoing and rightdoing, form a field. I will meet you there. The breeze at dawn has secrets to tell you: this place is a dream. Only a sleeper considers it real. Then death comes like the dawn, and you wake up laughing at what you thought was your grief.

I wish I could show you when you are lonely or in darkness the astonishing light of your own being. Your soul and my soul once sat together in the Beloved's womb playing footsie. Your heart and my heart are very, very old friends.

There was a four year old child whose next door neighbor was an elderly gentleman who had recently lost his wife. Upon seeing the man cry, the little boy went into the old gentleman's yard, climbed onto his lap, and just sat there. When his Mother asked what he had said to the neighbor, the little boy said, “Nothing, I just helped him cry.” Even after all this time the sun never says to the earth “You owe me.” Look what happens with a love like that. It lights the whole sky.
