Mundaka Upanishad :- When Brahman shines, everything shines after Brahman; by Brahman's light, everything is lighted.+

Brihadaranyaka Upanishad 1.3.28:~ “oṁ asato mā sad gamaya ~`tamaso mā jyotir gamaya~ mṛtyor mā amṛtaṁ gamaya~ oṁ śāntiḥ śāntiḥ śāntiḥ” ~

~Lead Us From the Unreal To the Real, Lead Us From Darkness To Light, Lead Us From Death To Immortality, Let There Be Peace, Peace, Peace.

The truth is very simple. It is very difficult to realize because it is lost in the dualistic knowledge we inherited, collected from different sources, different masters’ different gurus, different philosophies, different ideologies, different books, and scriptures.

All this accumulated knowledge is a mere hill of garbage.

Nothing is needed other than realizing the knowledge of the single stuff. The single stuff is the cause of the world in which we exist. And that single stuff itself is causeless. That single stuff is the Soul, which is present in the form of consciousness.

The Soul is the Self. Knowledge of the Soul, the Self, is Self-knowledge or Brahma Gnana or Atma Gnana. Atma Gnana is knowledge of God. Realizing God in this very life is your goal. God- realization itself is real worship.  

Remember:~ 

First Mundaka - Chapter 2 (8) - Fools, dwelling in darkness, but wise in their own conceit and puffed up with vain scholarship, wander about, being afflicted by many ills, like blind men led by the blind.

First Mundaka - Chapter 2 (9) - Children, immersed in ignorance in various ways, flatter themselves, saying: We have accomplished life's purpose. Because these performers of karma do not know the Truth owing to their attachment, they fall from heaven, misery-stricken, when the fruit of their work is exhausted.

First Mundaka - Chapter 2 (10) - Ignorant fools, regarding sacrifices and humanitarian works as the highest, do not know any higher good. Having enjoyed their reward on the heights of heaven, gained by good works, they enter again this world or a lower one.

First Mundaka - Chapter 2 (11) - But those wise men of tranquil minds who live in the forest on alms, practicing penances appropriate to their stations of life and contemplating such deities as Hiranyagarbha, depart, freed from impurities, by the Path of the Sun, to the place where that immortal Person dwells whose nature is imperishable.

First Mundaka - Chapter 2 (12) - Let a Brahmin, after having examined all these worlds that are gained by works, acquire freedom from desires: nothing that is eternal can be produced by what is not eternal. So that he may understand that Eternal, let him, fuel in hand, approach a Guru who is well versed in the Vedas and always devoted to Brahman. 

Second Mundaka - Chapter 2 (7) - He who knows all and understands all, and to whom belongs all the glory in the world-, Atman, is placed in the space in the effulgent abode of Brahman. It assumes the forms of the mind and leads the body and the senses. It dwells in the body, inside the heart. By the knowledge of that which shines as the blissful and immortal Atman, the wise behold Him fully in all things.

Second Mundaka - Chapter 2 (8) - The fetters of the heart are broken, all doubts are resolved, and all works cease to bear fruit when He is beheld who is both high and low.

Second Mundaka - Chapter 2 (9) - There the stainless and indivisible Brahman shines in the highest, golden sheath. It is pure; It is the Light of lights; It is That which they know who know the Self.

Second Mundaka - Chapter 2 (10) - The sun does not shine there, nor the moon and the stars, nor these lightnings, not to speak of this fire. When Brahman shines, everything shines after Brahman; by Brahman's light, everything is lighted.

Second Mundaka - Chapter 2 (11) - That immortal Brahman alone is before, that Brahman is behind, that Brahman is to the right and left. Brahman alone pervades everything above and below; this universe is that Supreme Brahman alone. 

Sage Sankara  gave out what was of most use to the greatest number of people. Therefore, in the commentaries on the Upanishads, such as the famous Mundaka, he gave the highest non-dual message of the identity of Atman and Brahman, revitalizing the philosophy and practice of Advaita, while in the commentaries on the Brahmasutra, he gave lesser teaching, positing both higher and lower Maya and higher and lower Brahman (Ishvara) to explain creation for those of lesser intellects until they were ready for the highest truth. 

The essence of Mundaka is: Do not be satisfied with rituals, yoga, etc. which are good in their own way, but inquire. Into what? Brahman and Atman are things you can never see. So do not inquire into them. Inquire into the world around you, which you can see. Science tells you it is passing away every second. Everything is dying repeatedly. Where is it going? Thus you follow up your inquiry into what you can lay hands on. How can you inquire into Atma which you cannot see? So first we deal with the known and seen, this inquiry leads up to the unknown in the end. :~Santthosh Kumaar
