In chapter 19 of Teachings of Presidents of the Church: David O. McKay, President McKay said, in part, the following:
The law of pure nature, survival of the fittest, is self-preservation at the sacrifice of all else; but in contrast to this the law of true spiritual life is, deny self for the good of others.

He also said
The greatest spiritual blessing comes from helping another.
What is “the greatest spiritual blessing”?
