Those who are seriously directed to the spiritual path should understand that their work at this moment is not to concern themselves with trying to save the world or even their relatives, but first of all with being saved themselves. This may sound selfish, but it is the very opposite of selfishness. Our primary function is to be concerned with only one thing, and that is that we attain conscious union with God. The rest of the world may have to battle out their woes by themselves while we stand by. We have to keep right on seeking the kingdom of God, seeking to attain our conscious union with God. If meanwhile the world swallows itself up, we cannot help it. It has always been that way.
There have been many civilizations destroyed in the past, and there are going to be quite a few destroyed from here on, but there has always been a remnant of those who were saved when civilizations were destroyed. Always after that destruction there were the few, who not only were saved, but left a record that helped save those of future generations. So it is that the Bible, the scriptures of all peoples and the mystical writings of all nations, these are the things that are helping you and me right now.
We are helped by those who have passed from our sight. Never believe that there is a retrograde step from developed spiritual consciousness. If an individual attains spiritual consciousness on earth, he is a blessing to everyone who brings himself within range of his consciousness and even to some who are not aware of what is going on. But when that individual leaves this human plane of life, his spiritually developed consciousness continues on just the same. It cannot be put into a grave. Those who have meditated with the I know:

‘I was never born and I will never die. That I was never confined in a physical body, much less will I ever be confined in a tomb.’

‘“I and my Father are one,” and therefore I am never limited to time, space, or place. I and the Father within are one, and that One is immortal. Therefore I go on forever and forever and forever. That I which I am is the state of consciousness which I am.’
