Om bhurbhuvah swah tatsaviturvarenyam bhargo devasya dhimahi dhiyo yo nah prachodayat
ॐ भूर्भुवः॒ स्वः॒
भ॒र्गो॑ दे॒वस्य॑ धीमहि।
धियो॒ यो नः॑ प्रचो॒दया॑त्॥
It is a prayer to the Almighty Supreme God, the Creator of entire cosmos, the essence of our life existence, who removes all our pains and sufferings and grants happiness beseeching His divine grace to imbibe within us His Divinity and Brilliance which may purify us and guide our righteous wisdom on the right path.
This is the most important prayer. All the problems of a person are solved if he is endowed with righteous wisdom. Having far-sighted wisdom, a man is neither entangled in avoidable calamity nor does he tread a wrong path.
