Om! That (Brahman) is infinite, and this (universe) is infinite. The infinite proceeds from the infinite. (Then) taking the infinitude of the infinite (universe), It remains as the infinite (Brahman) alone.
Om! Let there be Peace in me! Let there be Peace in my environment! Let there be Peace in the forces that act on me!
Now let us explain Advyataraka Upanishad for Yogis, Sannyasis (Hermits), Jitendriyas (Controller of the senses) and seekers who are full of the six gunas like Sham, Dam etc.
He merges with Brahma by keeping his eyes close or half-opened to establish yourself at the upper place of brows as - "I am in garb of the heart" and by feeling true pleasure and observes Brahma in the light of that pleasure Un deviated.
Taraka Brahma is considered what is perfect knowledge (Brahma) with excellent splendour and save from womb, birth, old age, death and murder like sins. Assuming the living-organisms and God both covered by the illusion (Maya) who abandons all others by saying "it is unlimited" (Neti-Neti), can attain the residual i.e. "one or unique Brahma". (The residual after abandoning material ties is the true and purified knowledge).
In order to avail the shelter of that perfect knowledge (Parabrahma), the research of three aims is the only act possible.
In the middle part of the body of that Yogi, the Brahma nerve "susumnä" (spinal nerve) is luminated with the light of moon. It is extended from Mulädhära (at the anus and in the middle of genital organs) to the brahmarandhra (where the spinal cord penetrates into brain). In the middle portion of this nerve, the micro shaped Kundalini is existed. This "Kundalini" is shining like crores of electric currents. The man becomes entitle to avail emancipation by exoneration of all sins committed. The person who sees regularly the splendour existed in the specific region on the brain, becomes a perfect devotee and achieves the desired success. By keeping close the holes of both ears by the tips of the index fingers a hissing sound (like that of a snake) is heard. By focusing the mind and observing the blue flame in the middle of eyes, most pleasure is felt. The same is observed in the heart too. The devotee keeping the desire for emancipation (Mumuksu) should exercise the "inner aims" (worth feeling in the heart).
Note: The man gets impetus to commit crime due to attachment for the extraneous pleasures. This tendency to commit an offence arises on the basis of the above attachments. On being observance through to the competency of the Kundalini existing in the heart, man becomes confident that the source of pleasure lies in the heart. This is the reason the offensive tendency does not emerge for the extraneous achievements.
Now, the characteristics of extraneous aim" are described. He is called the real Yogi who can regularly see the element of ether, of colour yellowish white, the ether of reddish colour, blue and dark colour from a distance from the point of nose to four, six, eight, ten or twelve fingers respectively. By observing in ether (the void place) by that dynamic sight, the rays of light are seen apparently clear. A Yogi can only see those divine rays. When in both corners of eyes, the ray of light (Mayükha) is seen like the hot gold, his sight then is concentrated. The "Yogl" attains immortality who sees that ray at a distance of twelve fingers. The person who sees that ray from ether irrespective of the distance above head, become the perfect Yogi.
We now describe the characteristics of the "middle aim". Who sees the integrated sun in the colours, citra etc. and in the circular shape, like the flame of fire and the space without them, becomes analogous to that shape and enshrined the same way. Further, he becomes ether form merely by observing him (sun). He is luminated with the stars and becomes supreme ether like the dark of the dawn. The "Great Ether" (Mahakasa) is luminated as the fire of the time (Kalägni). The "element of ether" is of the best light and acute flame. The "ether of sun" (SaryAkasa) is analogous to the crore suns. The fire ethers thus, enshrined externally and internally are the aims of the "taraka-brahma". The observer of sky through this procedure, becomes entitle to emancipation by cutting-off all ties like the ether itself. The aim of Taraka has been said endower with un-imagined fruits.
Two methods of this "Taraka Yoga" have been explained. The first is the half-first and second is second-successive. The hymn referred to it in this context is - "This yoga is of two kinds the first is the first half and the other is the second half. The former has been said "Taraka" and the later Amanaska (void mind)."
We see the sun and moon by our täraka (cornea). As we see the sun and moon in this universe (Brahmanda), we should in the similar fashion, always observe the sun and moon under presumption, in the middle of our head in the form of universe and considering them of the same form, ponder upon them with concentration because all sensory organs start engrossing in luxuries if such is not presumed. It is, therefore, necessary for a devotee that he should develop a trend to research regularly the Taraka through his intuition.
Two methods have been told for this "taraka". The first is tangible and the other is intangible. Whatever in the mind is called tangible Taraka and the Taraka existing outside both brows is intangible. While discussing about the inner matters, one should do the exercise through concentration. By analysis regularly in one's heart (full of Satva merit), the luminating perfect Brahma in garb of true pleasure above the cornea of eyes is seen. It reveals that the Brahma is full of splendour and in white colour. That Brahma should be seen by intuition of the eyes. It makes able to know that the Brahma is full of splendour and white colour. The intangible Taraka too, is known through the same process of the mind's eyes. The mind is dependent to the eyes in the matter of seeing the complexion. Analogous to the external, the internal cognisance of the complexion is also made by these two. This is the reason; the light of Taraka becomes by the eyes including the mind.
The man who sees the light with splendour a little above the place where both brows are by his intuition, is the Täraka Yogi. By establishing the fair union of "taraka" with the mind, both brows should be stayed above a little distance. This is called the first half of Taraka. The second-half portion is called intangible. Above the root of palate, a great circle of rays is existed. The meditation of the same is the aim of yogis. It is the cause for the axioms like Animã etc.
When the sight (power to observe) competent to see the internal and external aim becomes stable, this stage is called the Sambhavi Mudra (Posture). The residence of the scholar, having this posture is treated very sacrosanct. and all worlds become sacred only by his single sight. The worshipper of this supreme Yogi becomes entitle to emancipation.
The internal aim turns into a white flame. The internal aim (Antarlaksya) is existed within the sixteen arts or the flame existing in the cavity of wit or the luminating flame existed in the lotus of thousand petals and it is known only when the supreme teacher graces with his teaching. This philosophy is the root of etiquette.
The person known to Vedas, enlightened, devotee to lord Visnu, liberated from the defect like manipulation etc. expert in yoga, loyal to yoga, yogätma (devotee to yoga),
sacrosanct, obedient to teacher and specially engaged in the attainment of God is called a teacher by virtue of all these characteristics.
The literal meaning of "gu" letter is darkness and "ru" means competent to resist the darkness. Therefore, the composite meaning of the word "Guru" is a person who drives away the ignorance.
Guru is the supreme soul and supreme Brahma (knowledge). Teacher (Guru) too is the supreme motion, he is Paravidya (metaphysics), and he is the best shelter.
Teacher (guru) is the climax and the supreme wealth. It should be presumed that the person who preaches the best is the best teacher or the teacher of the teachers.
The person who once recite this Upanishad or guru, crosses peacefully this worldly ocean. The sins accumulated since birth are decayed. All desires and ambitions are fulfilled. All industry meets success and achievement. The person known to this is the real scholar of Upanishad. This is the Upanishad, a sole cause for all achievements.
Om! That (Brahman) is infinite, and this (universe) is infinite. The infinite proceeds from the infinite. (Then) taking the infinitude of the infinite (universe), It remains as the infinite (Brahman) alone.
Om! Let there be Peace in me! Let there be Peace in my environment! Let there be Peace in the forces that act on me!
