NEED AND WANT.
If you are dying of thirst in the desert, you need water – not lemonade. If you ask for water, it is your need. If you ask for barley water, it is a want. But if you can get good water, it is not necessary to drink muddy water to kill your desire for drinking. Drink good water. Neither lemonade nor muddy water, but pure, simple water.
Lord Meher, pp. 2151 – 2153.
