"The temporary feelings of good and evil, love and hatred, that have been aroused by surroundings and changing external conditions, are only momentary reactions that have their cause in the defilement accumulated by the human mind.

Behind the desires and worldly passions which the mind entertains, there abides, clear and undefiled, the fundamental and true essence of mind. Water is round in a round receptacle and square in a square one, but water itself has no particular shape.

People often forget this fact.
People see this good and that bad, they like this and dislike that, and they discriminate existence from non-existence; and then, being caught in these entanglements and becoming attached to them, they suffer."
