ॐ ये त्रिश्प्तः परियन्ति  विश्वा रूपाणि विभ्र्तः I
वाचस्पतिर्बला तेषाम तन्वो अद्य दधातु मे II

Oh God, you created this creation with twenty one elements*.  By them alone countless forms came into being and by your strength they are existing everywhere in the universe. The same elements constitute our body as well. O Lord! May these elements keep us strong, and their quality should remain intact as it is. Let us strive to keep these pure and do nothing to pollute them in any way.

* 21 Elements:
5 Senses of knowledge: eyes, ears, nose, tongue, skin.
5 Organs of physical functions: mouth, hands, feet, rectum, genitals.
5 Chief elements: earth, water, air, fire, ether.
5 Objects of senses: sight, sound, smell, taste, touch.
1 Soul (Self)

ॐ यज्जाग्रतो दूरमुदैति दैवं, तदु सुप्तस्य तथैवैति .
दूरंगमं ज्योतिषां ज्योतिरेकं, तन्मे मनः शिवसंकल्पमस्तु .

Om Yajjagrato Doormudaiti Daivam , Tadu Suptasya Tathaivaiti.
Doorangamam Jyotishaam Jyotirekam, Tanmay Mna Shiv-Sankalapamastu.

O God! The mind of man flees fast and far away in awakened state. It acts the same way during sleep as well.
It is the chief among all senses; such mind should be of pure thoughts.

ॐ भद्रं कर्णेभिः शृणुयाम देवा,
भद्रं पश्येमाक्षिभिर्यजत्राह १
स्थिर्रैरान्गैह्स्तुश्तुवान्
सस्तानूभी ,
व्यशेमही देवहितं यदायुः

Om Bhadram Karnebhih Shrunuyama Devaha,
Bhadram Pashye-makshbhi-ryajatraha
Sthirai-rnagai-stushtvaam-sastanoobhi,
Rvyashemahhi devhitam ydaayuh.

O God, may we hear with our ears what is auspicious,
May we see with our eyes what is auspicious,
May our whole body be healthy and diseaseless,
May we always keep the Five Elements, which are the basis of our life, clean and pure.

om bhūr bhuvah svah
tat savitur varenyam
bhargo devasya dhīmahi
dhiyo yo nah pracodayāt

Meaning: Om, the Parbrahm or Supreme Soul (God) pervades the three worlds – the Earth (bhu), the space (bhuvah) and beyond the space (svah) where exists nothing but God alone in His purest form. That God is in the form of infinite light, which is beyond comparison. Let us meditate on that divine light of the Supreme Soul. Its meditation will lead us to God realization.

Poetry:
Three worlds you know,
certainly these come to sight;
The bhu, bhuva and svah,
shine by His limitless light.

Bhu is this Earth,
we all dwell in this place;
Bhuva is the universe,
svah is beyond the space.

God pervades all,
His infinite light is all over;
They behold that light,
to Him alone who adore.

Behold His immense light,
it purifies the intelligence;
Vedas call Him Ritambhra (Supreme wisdom),
that intelligence who attains.

Gayatri sums up the Vedic wisdom,
Om is the soul of Gayatri, wise discrens;
When Om sets into life-breaths,
never to the world one returns.
