This is the essence of selfishness and the kernel of the Great Fall from grace.
Ignorance is the product of the act "to ignore." By ignoring God and our spiritual heritage we were left to cling to physical reality as our "foundation of sand."
We turned our backs on the light and buried our consciousness in darkness. This was the great "death"--the long sleep of immortal spirit--whose dreams are the conscious reality of these Homo sapiens hosts.
Ego is at the heart of this ignorance. Ego is the sense of entitlement to be right and frequently to make others wrong. Ego is the matrix of mortal dichotomies--from good-evil and generous-selfish to wisdom-stupidity and compassion-indifference.
I hope to wipe the ignorance from my own soul and wish that blessedness on everyone else, too.
