यत्सत्तया जगद्सत्वं यत्पकाशेन भायुतम् ।
नंदनं च यदानंदात् तस्मै श्री गुरवे नमः ॥
by which existence the world appears; and by which light the world is bright; and by which bliss the world derives happiness; to that GURU I bow down.
मन्नाथ श्री जगन्नथो मद्गुरु स्त्रिजगद्गुरुः ।
ममाऽत्मा सर्वभूतात्मा तस्मै श्री गुरवे नमः ॥
My lord is the lord of the universe (jagat); my guru is the guru of the three worlds; my atma is the atma of all the beings; I bow down to such lord = guru = self!
अखंड मंडलाकारं व्याप्तं येन चराचरम्
तत्पदं दर्शितं येन तस्मै श्रीगुरवे नमः
"akhanda mandalaakaaram" in which the whole of living and non-living beings appear, that word "tat" has been shown to me by the GURU. I bow down to such guru.
देहे जीवत्वमापन्नं चैतन्यं निष्कलं परम्
त्वं पदम् दर्शितं येन तस्मै श्रीगुरवे नमः
That which entered the body, that "jeeva chaitanyam" which is never tainted by anything, that word "tvam" has been shown to be by the GURU. I bow down to such guru.
अखंडं परमार्थं सत् ऐक्यं च त्वं तदोश्शुभम्
असिना दर्शितं येन तस्मै श्रीगुरवे नमः
akhandam, paramaardham that truth and body, this are one and the same that is shown by the word "asi". Such word is shown to me by the GURU. I bow down to the Guru.
Having said that, a small word of caution.
गुरवो बहवस्सन्ति शिष्य वित्तापहारकाः
दुर्लभ स्स गुरुर्लोके शिष्य संताप हारकः
guravah, bahavah, santi, sishya, vitta, apahaarakaaH.
durlabhaH, saH, guruH, loke, sishya, saMtaapa, haarakaH
There are lot of gurus who take away the wealth of the sishya; it is indeed difficult to get a guru who will take away the "worldly misery" of the sishya.
-- From skanda purana; GURU GEETHA.
(Most famous "gururbrahma, gururvishnu gurudevo maheswarah, gurussakshaat parabrahma tasmai sri gurave namaha" is also from this chapter of Skanda Purana only.)
