Existence itself stands in need of nothing, for it lacks nothing, whereas everything else needs it, because outside of it there is nothing. Nothingness stands in need of existence, as a sick man lacks health and is in need. Health has no need of a sick man. To want nothing, therefore, characterizes the highest perfection, is fullest and purest existence.
Meister EckhartIt is permissible to take life's blessings with both hands provided thou dost know thyself prepared in the opposite event to take them just as gladly. This applies to food and friends and kindred, to anything God gives and takes away... As long as God is satisfied do thou rest content. If he is pleased to want something else of thee, still rest content.
Meister Eckhart
