The first step is to measure whatever can be easily measured.
This is okay as far as it goes,
The second step is to disregard that which cannot be easily measured
or to give it an arbitrary value.
This is artificial and misleading.
The third step is to presume that what cannot be measured
isn’t really important.
This is blindness.
The fourth step is to say that what can’t be measured
doesn’t really exist.
This is suicide.
— Robert MacNamara
Everything in this world cannot be explained by logic or in scientific terms. But our system is such that a person looks for a scientific explanation for everything. Yes, by all means look for scientific explanations but don’t stop at that, it is not the end. Some things can only be explained by pure awareness of the being, logic and scientific explanations fail here. The person has to have a direct experience to understand. For example: Love
It is difficult to understand love,
But it is easy to feel it,
It is difficult to derive an equation and prove love,
But it is easy to experience and love.
Similarly realization of self is something that can only be understood when a person experiences it. Mind is the only connection to realize our true Self. Mind is the only starting point to uncover the hidden inner world. It is only by training the mind that a person can open the doors to his inner self within his mind.
