It does not come easily to the mind to be self-reflective.
Therefore, the mind has to be trained and taught.
But it comes very easily even to the uneducated mind to gape and grope. Look at things outside, and then go for them.
But does it equally easily to the mind to turn inwards and be self-reflective?
That does not come.
We are designed that way.
Neither can the fingers hold the Truth, nor is the mind designed to seek the Truth.
