Gurumurti Dakshinamurty

यस्यैव स्फुरणम् सदात्मकमसत्कल्पार्थकं भासते
साक्षात्तत्त्वमसीति वेदवचसा यो बोधयत्याश्रितान्।
यत्साक्षात्करणात्भवेन्न पुनरावृत्तिर्भवाम्भोनिधौ
तस्मै श्री गुरुमूर्तये नम इदं श्रीदक्षिणामूर्तये ॥

             - Dakshinamurty Stotram by Adi Shankaracharya: stanza ॥3॥

owing to the Radiance of Whom, the Real Self manifests as the Ostensible Universe,
(and) the direct experience of the Vedic words, tat-tavam-asi, is appercieved by those who have sought refuge (in Him);
"That", Whose Realisation, becomes instrumental cause, of revisitation into the ocean of worldly existence,*
unto Him, the manifestation of Guru, Shri Dakshinamurty, is our obeisance.

[*until “That” (as in “tattvamasi” = "thou art That") is Realised,
the cycle of rebirth into (that ostensible) world continues.]
