Jesus said:~ "Know what is in front of your face, and what is hidden from you will be disclosed to you.+

The truth-realization is to investigate the truth of the physical existence or the universe.  It seeks the meaning of all that is seen, known, believed, and experienced as A  person and of the world that confronts him. 

That is why Jesus said:~  "Know what is in front of your face, and what is hidden from you will be disclosed to you. (THE GOSPEL OF THOMAS- Saying 5)

It means one has to know the world which confronts him confronts to realize his body and the world are made of the same essence and that essence is Spirit (father). 

That is why Sage Sankara said:~ One must first know what is before him. If he cannot know that, what else can he know or understand? If he gives up the external world in his inquiry, he cannot get the whole truth.

Sage Sankara said:~VC ~63. Without causing the objective universe to vanish and without knowing the truth of the Self, how is one to achieve Liberation by the mere utterance of the word Brahman? — It would result merely in an effort of speech.

Jesus said:~"Those who seek should not stop seeking until they find. When they find, they will be disturbed. When they are disturbed, they will marvel, and will reign over all." (Gospel of Thomas 2)

"The Kingdom of God is inside you and all around you, Not in a mansion of wood and stone.  Split a piece of wood and God is there, Lift a stone, and you will find God." (Gospel of Thomas)

Man learns from his experience that he is ever liable to err, which leads to disappointment and suffering. Naturally, it, therefore, seeks to avoid a repetition of an error. Thus, he has to make efforts at seeking truth or freedom from error.  But because of ignorance, he fails to investigate the truth of true existence. The ignorance is present in the form of ‘I’.

Deeper self-search itself is meditation. People think they don’t make progress. It is because they are not going deep enough, and they assume self- realization is some physical experience like yogic Samadhi or yogic bliss.   Self-awareness comes naturally when one becomes fully aware with the firm conviction of the existence of the formless witness of the three states.   The formless witness, which is consciousness, exists prior to the three states. Thus, it is necessary for the seeker to realize what exists prior to the appearance of the three states.  

   

Though the man is able to exercise his reason, yet he does not get to a stage at which there can be no disappointment or suffering. He has to make his "trials" as often as is necessary.  But the pity of it is that he does not realize that he has not attained the truth, unless doubt arises as a result of disappointments or sufferings, of his own or of others.

Jesus said: ~  Do not throw your pearls before pigs, lest they trample them underfoot and turn to attack you. (Matthew -7:6)

~ Jesus meant Self-knowledge or Knowledge of Spirit or  Brahma Gnana (pearls) should not be given to the ignorant populace (pigs).

Many believe, that spirituality and religion are considered interconnected, but it is not so. Religion is based on the false self (ego or body or you) and it is limited to the false experience (universe) while spirituality transcends race, religion, gender, language and nationality, and the universe.  Spirituality is based on the Soul, the Self. From the standpoint of the Soul, the Self,  the universe in which we exist is merely an illusion.:~Santthosh Kumaar
