When the sage points to the moon, the idiot looks at the finger.”
Experts come and study the nature of the finger. They form theories and doctrines around it. They organize the Church of the Finger and create rules and laws about how the finger should point, when it should point and in what angle it should point.
Amidst all this, they do not see the moon.
Scriptures and religions are all pointers. The Bible is not God, and the Koran is not God. People have built entire belief systems and organizations, have fought wars and endured torture and hardships, for the sake of furthering their beliefs.
But they have missed God.
