Significance of Gayatri Mantra.

 "oṃ bhūr bhuvaḥ svaḥ

tat savitur vareṇyaṃ

bhargo devasya dhīmahi

dhiyo yo naḥ prachodayāt "

– Rigveda 3.62.10

In the Vedic tradition, a child is first initiated to the highest knowledge - the Gayatri mantra. After that, all other forms of education are given. It is said in the scriptures that women are also eligible to learn the Vedas and chanting the Gayatri mantra. The ideal time to chant is the transitory hours of dawn and dusk. The times when the sun has set but it is neither dark nor light and when the night has passed and the day is yet to begin. In these moments, the mind also enters an altered state of consciousness. The moments belong neither to the previous state nor the next. It is the right time to be focused on the Self instead of being caught up in changes or movement. In these hours, the mind can easily be confused and slip into inertia, lethargy, negativity and so on or be elevated and move into a meditative state radiating positivity. Chanting the Gayatri mantra rejuvenates the mind and maintains it in an elevated and energized state.
