Truth not to be understood. It is to be felt.

-- ## Paragraph and ideas need to be put appropriately.

Vedas and Truth is not to understand. They are to be felt. All that is documented and discussed with great complexity can become your personal experience. Like as you grew up you don't fascinate and discuss about many things (as a poor ex wireless devices such as cell phone) as they are you personal experience. You no more discuss, talk, logically try understanding it (but 40 years ago if you would have seen it..) . In fact, discussions and logic are not needed about what can be your personal experience, I think (for later is a way better state of understanding than former).
A) If you are fortunate enough to have sensed the Truthfulness and Universality of words coming out of Spiritual understanding (for ex. that of Swami Ji's and other Tatva-Gyani Atmasakshatkari Sant) (specially if you find yourself refer to them in your quest of Truth)... B) and you don't find it appropriate to just go on living in the ways of Today ... you see that humans have not reached perfection and there is a need to continue journey and need to strive to find Truth ... C) and if You can have faith............... then You need to figure out how to reach to words and personal proximity of any one who has undergone that journey and has Vedas as his personal experience. It is possible to achieve that in this very life.. before you die. In fact, it is your reality. It is not something you have to reach to or have to become. It is you. Remove impurity and purity is already there. So with much less effort than you are putting now you can shortly figure it out in your very existence. (A lock is opened very easily with right key and turning it into right direction.. otherwise it is very hard. I am suggesting you the easier way.)
Other Religions fix your appointment with God after death with the grace and sifarish of son/messenger-of-God if you be nice in your life. Hindu Dharma (Religion is not the correct translation of Dharma by their inherent meanings) asks you to meet HIM (consider the symbolic name of TRUTH) in your very life. In fat, it tells that this is the purpose of your Human life (answer to point 1). It reveals that Truth is your default experience.
Who in here will disagree that Feeling is a better state of understanding than logic? If the Marijuana example confuses you then the fact is it doesn't last. Illusions are momentarily. I guess I forgot to mention that the live encounter of that reality is not momentary. Once attained, one is crystal clear that it's the reality. He/She sees, feels and realizes every moment the reality of it. Every thing in surrounding he used to interpret the way we do as of now, he find them obeying that Truth-ness.
Ok, at least, you will, I hope, accept you may not be having some kind of knowledge. Also, you all, I hope, will accept that knowledge changes the viewpoint and attitude (pls feel free to add any other thing you feel chagnes as well) . And once you have the knowledge you will never have that viewpoint and attitude you earlier had out of darkness about subject/entity/. It is not illusion. Otherwise, you will be back to square one after some time.
Actually It's all about knowledge. Knowledge is the key. God, Soul, Absoluteness, What am I, Self-Realization.. All are about Knowledge.
You may tell a child that Fire is hot and you must now touch it. But that will be just the Information for him. It's only when he can't resist it's beauty and tries to hold it he actually gains the knowledge. So Knowledge is about experiencing it (something felt by your own).
... and : Unfortunately its not as easy and straightforward case as it was for that 'child' who saw fire for the first time. (think about the difference of understanding he will get between [he trying to logically understand Fire with his level of understanding] and [trying it himself]). .........
.......... Knowledge can have complexity. We can't claim humans including scientist posses all kind of knowledge (excluding realized saints). Hence, we can't say we have seen all kind of complexity (I hope you will agree). We can't claim that there is no complexity human mind can not afford to understand. We can't deny the fact that a Complexity can be beyond grasp of Human mind in a Human life span. But once felt you suddenly are different. Now you have that knowledge and your viewpoint & attitude will be the likes of Swami Ji (It was, I hope you will agree, certainly not what a common man follow no matter how rich and powerful he is). Sorry for talking in terms which may seem very strange, may be crap/nonsense or very superficial. But the underlying topic is extra-ordinary.
