mind

the great enigma for psychologists and philosophers is the mind

Beware the Rattlesnake of the Mind.

Some important ideas from the book of early Christians which is called Philokalia:

From Spiritual Directions of Diadochus of Photiki

The acme of faith is… immersion of the mind in God.

The acme of freedom from wealth is to desire to be possessionless even as others desire to possess.

The acme of humbleness is to forget unfalteringly good deeds of oneself.

The acme of love is to enhance your friendly attitude to those who insult and revile you.

The rigidity of one's religious beliefs diminishes with the presence of faith.  Fanatacism is a grasping for order in a mind without peace and without faith.

There is a vast region of enormous potential located somewhere between your ears.

She runs up into the light surprised
Her arms are opened
Her mind's eye is
Seeing things from a better side than most can dream
