Holiness alone is undying peace. Self-control leads to it, and the ever-increasing Light of Wisdom guides the pilgrim on his way. It is partaken of in a measure as soon as the path of virtue is entered upon, but it is only realized in its fullness when self disappears in the consummation of a stainless life.
This is peace,
To conquer love of self and lust of life,
To tear deep-rooted passion from the heart
To still the inward strife.
If, O reader! you would realize the Light that never fades, the joy that never ends, and the tranquility that cannot be disturbed; if you would leave behind forever your sins, your sorrows, your anxieties and perplexities; if, I say, you would partake of this salvation, this supremely glorious Life, then conquer yourself. Bring every thought, every impulse, every desire into perfect obedience to the divine power resident within you. There is no other way to peace but this, and if you refuse to walk it, your much praying and your strict adherence to ritual will be fruitless and unavailing, and neither gods nor angels can help you. Only to him that overcometh is given the white stone of the regenerate life, on which is written the New and Ineffable Name.
~ James Allen, From Poverty to Power (1901)
