GAYATRI MANTRA AND ITS SCIENTIFIC INTERPRETATION
Gayatri mantra has been bestowed the greatest importance in Vedic dharma.  This
mantra has also been termed as Savitri and Ved-Mata, the mother of the Vedas.
Om bhur bhuvah swah
Tat savitur varenyam
Bhargo devasya dheemahi
Dhiyo yo nah prachodayat

The literal meaning of the mantra is:
O God! You are Omnipresent, Omnipotent and Almighty, You are all Light. You are all Knowledge and Bliss. You are Destroyer of fear, You are Creator of this Universe, You are the Greatest of all. We bow and meditate upon Your light. You guide our intellect in the right direction.

The mantra, however, has a great scientific importance too, which somehow got lost in the literary tradition. The modern astrophysics and astronomy tell us that our Galaxy called Milky Way or Akash-Ganga contains approximately 100,000 million of stars. Each star is like our sun having its own planet system. We know that the moon moves round the earth and the earth moves round the sun along with the moon. All planets round the sun. Each of the above bodies revolves round at its own axis as well. Our sun along with its family takes one round of
the galactic center in 22.5 crore years. All galaxies including ours are moving away at a terrific velocity of 20,000 miles per second.

An alternative scientific meaning of the mantra, line by line is provided below.  
Line 1:
OM BHUR BHUVAH SWAH:
Bhur the earth, bhuvah the planets (solar family), swah the Galaxy.  We observe
that when an ordinary fan with a speed of 900 RPM (rotations Per minute) moves,
it makes noise. Then, one can imagine, what great noise would be created when
the galaxies move with a speed of 20,000 miles per second. This is what this
portion of the mantra explains that the sound produced due to the fast-moving
earth, planets and galaxies is Om. The sound was heard during meditation by
Rishi Vishvamitra, who mentioned it to other colleagues. All of them, then
unanimously decided to call this sound Om the name of God, because this sound is
available in all the three periods of time, hence it is set (permanent).
Therefore, it was the first ever revolutionary idea to identify formless God
with a specific title (form) called upadhi. Until that time, everybody
recognized God as formless and nobody was prepared to accept this new idea. In
the Gita also, it is said, "Om-iti ekaksharam brahma", meaning that the name of
the Supreme is Om , which contains only one syllable (8/12). This sound Om heard
during samadhi was called by all the seers nada-brahma a very great noise), but
not a noise that is normally heard beyond a specific amplitude and limits of
decibels suited to human hearing. Hence the rishis called this
sound Udgith musical sound of the above, i.e., heaven. They also noticed that
the infinite mass of galaxies moving with a velocity of 20,000 miles/second was
generating a kinetic energy = 1/2 MV2 and this was balancing the total energy
consumption of the cosmos. Hence they named it Pranavah, which means the body
(vapu) or store house of energy (prana).

Line 2: TAT SAVITUR VARENYAM:
Tat that (God), savitur the sun (star), varenyam worthy of bowing or respect.
Once the form of a person along with the name is known to us, we may locate the
specific person.Hence the two titles (upadhi) provide the solid ground to
identify the formless God, Vishvamitra suggested. He told us that we could know
(realize) the unknowable formless God through the known factors, viz., sound Om
and light of suns (stars). A mathematician can solve an equation x2+y2=4; if
x=2; then y can be known and so on. An engineer can measure the width of a river
even by standing at the riverbank just by drawing a triangle. So was the
scientific method suggested by Vishvamitra in the mantra in the next portion as
under:-

Line 3:
BHARGO DEVASYA DHEEMAHI:
Bhargo the light, devasya of the deity, dheemahi we should meditate.  The rishi
instructs us to meditate upon the available form (light of suns) to discover the
formless Creator (God). Also he wants us to do japa of the word Om (this is
understood in the Mantra). This is how the sage wants us to proceed, but there
is a great problem to realize it, as the human mind is so shaky and restless
that without the grace of the Supreme (Brahma) it cannot be controlled. Hence
Vishvamitra suggests the way to pray Him as under:

Line 4:
DHIYO YO NAH PRACHODAYAT
Dhiyo (intellect), yo (who), nah (we all), prachodayat (guide to right
Direction). O God! Deploy our intellect on the right path. Full scientific
interpretation of the Mantra: The earth (bhur), the planets (bhuvah), and the
galaxies (swah) are moving at a very great velocity, the sound produced is Om ,
(the name of formless God.) That God (tat), who manifests Himself in the form of
light of suns (savitur) is worthy of bowing/respect (varenyam). We all,
therefore, should meditate (dheemahi) upon the light (bhargo) of that deity
(devasya) and also do chanting of Om. May He (yo) guide in right direction
(prachodayat) our(nah) intellect dhiyo.

The important points hinted in the mantra are

1) The total kinetic energy generated by the movement of galaxies acts as an
umbrella and balances the total energy consumption of the cosmos. Hence it was
named as the Pranavah (body of energy). This is equal to 1/2 mv2
(Mass of galaxies x square of velocity.)
2) Realizing the great importance of the syllable OM , the other later date
religions adopted this word with a slight change in accent,  viz., Amen and Ameen.
So Memorize and Chant Mantra everyday

Thiruaiyaru Thyagaraja Aradhana Festival

Tyagaraja(1767-1847) was the greatest among the music composers of South India and one of the musical prodigies of all time.  He was the father of modern Karnataka music and his works are of delicate spirituality, full of melodic beauty and in the highest sense artistic.  As a child he as already remarkable for his predilection for music and a gift for composing and wrote his first song when he was hardly 13.  Soon he reached the loftiest pinnacle of musical fames and composed the grandest songs ever written and two music plays of uneqalled beauty.  He exerted the greatest influence upon musical art in South India during the 18th and 19th centuries and revolutionized the very nature of Karnataka music.  His songs are accepted today as the only adequate interpretation of classical Karnataka music from both the music and the sahitya points of view

When a great person achieves distinction in two fields of human endeavour which are related, it is difficult of assess the value of his eminence in any one of them separately. Tyagaraja was a great saint as well as a great musician. In his mind, music played a subordinate a part and devotion to his chosen deity played the dominating part. He used music as an appropriate vehicle for the journey towards salvation. Posterity, however, remembers him primarily as a great composer and the association of religion, with his music is very often taken as part of the musical tradition of India of which he was a leading light. This difference in approach between the composer himself and the inheritors of his contribution has led to estimations of his contribution has led to estimations of his music based on spiritual sympathy and panegyrics of is sainthood based on musical appreciation.

Sri Tyagaraja attained mukti in the year 1847. The mortal remains of this great soul were interred on the banks of the Kaveri and a Brindavana was erected over the spot.The Umayalpuram brothers, Krishna Bhagavatar and Sundara Bhagaavatar and othes used to go to the Samadhi every year on the Pushya Bahula panchami day, do puja and then return home and perform the aradhana proper. From the year 1907 onwards, the Samadhi Utsava entered a new phase. Tillisthanam Narasimha Bhagavatar and Panju Bhagavatar, along with Tiruch Govindasami Pillai, the great violinist, began to celebrate the festival on a grand scale.
