As to spiritual development, there are different influences which may be considered as spiritual influences, and such we need in our life; such as the influence of kindness, of compassion, the influence of Providence, inspiration, cure, health, wisdom, power, and so forth. These being spiritual influences the mystics have names for them - for each of these influences - and they call them the sacred names of God. There are perhaps a hundred of such names or more which the mystics use, and each of these names has been practiced by them for thousands of years. The effect of these names works sometimes most wonderfully.
