When you clutch at anything and try to make it your own with an egoistic sense of possession, then however beautiful and wonderful it may be, it loses its value and becomes ordinary.

It is not a demand to ask for things that one finds helpful, but it becomes a demand if there enters into it a feeling of claim, resentment when it is not conceded or other vital reactions. Be on your guard against any invasion by these reactions; the vital can only be conquered and changed and the physical opened up on a basis of faith and surrender and the psychic response overpowering all others.
