First and foremost be clear in your thought and aspiration about what you want. You want to know about the real nature of the world or know yourself or both. Once you are clear about it then you should read all that has been written on the subject by those whom you can intuitively trust or else seek inwardly for a Guide, the Guru who can help you find. Or else turn to a Deity or form of the Divine who represents to you the Higher Power. Alternatively read books of guidance and try to understand what they say and follow the guidance. It is like entering a School of higher knowledge. One doesn’t try things randomly. One needs someone to guide.
Of course reason and analysis cannot reveal all the mysteries of life and creation because it depends upon our imperfect sensory inputs. Also it is important to keep a balance. Everything including concentration should be in moderation. An excess in any direction is not good. You must also do physical exercises and study well so that the body and brain develops to receive the higher consciousness when you are ready.
Affectionately,
