In his autobiography, Russell M. Nelson had a dream that, if President Harold B. Lee survived beyond his sudden death in December 1973, Lee, not President Kimball, would have received the revelation concerning the priesthood/temple restriction:
In
the dream there were two vivid messages: first, that if President Lee had gone
on living, a very severe affliction would have developed in his body which, if
allowed to progress, would have given him great pain, suffering, and
incapacity. The medical details of this were dreadful and distressing. He said
his sudden death in December 1973 was brought about as an act of love and
mercy, for the Lord wished to spare him and the Church the misery that
otherwise would have ensued. His second message was that the revelations
received and the actions subsequently taken by President Kimball were the very
same as would have been received and performed by President Lee had he remained
as the prophet. President Lee exclaimed that the Lord gives His will to His
living prophet regardless of who the prophet is at the time, for the Lord
indeed is directing his Church. (Russell M. Nelson, From Heart to Heart: An
Autobiography [Salt Lake City: Quality Press, Inc., 1979], 159-60)
