That is the phenomenon of modern days alone, that man by hundreds and by thousands despairs of his own immortality.

And yet the deepest conviction of humanity, the deepest thought in man, is the persistence of himself, the "I" that cannot die.

And with one great generalisation, and one method, Theosophy asserts at once the deathlessness of man and the existence of God; for it says to man, as it was ever said in the ancient days: "The proof of God is not without you but within you." All the greatest teachers have reiterated that message, so full of hope and comfort; for it shuts none out from knowledge.

What is the method?
Strip away your senses, and you find the mind; strip away the mind, and you find the pure reason; strip away the pure reason, and you find the will-to-live; strip away the will-to-live, and you find Spirit as a unit; strike away the limitations of the Spirit, and you find God.
Those are the steps: told in ancient days, repeated now.

"Lose your life," said the Christ, "and you shall find it to life eternal." That is true: let go everything that you can let go; you cannot let go yourself, and in the impossibility of losing yourself you find the certainty of the Self Universal, the Universal Life.
Pass again from that to another religious point.
