Guru

Scroll down to read in English :
गुरुवक्त्रे स्थितं ब्रह्म प्राप्यते तत्प्रसादतः |
गुरोर्ध्यानं सदा कुर्यात् पुरूषं स्वैरिणी यथा ||

Meaning: Brahman (in the form of words) resides in the mouth of the Guru, and one attains Brahman by the grace of the Guru. One should meditate on His Guru at all times, just as a devoted wife thinks of her husband only.
