महेश्वरः

यो वेदादौ स्व॑रः प्रो॒क्तो॒ वे॒दान्ते॑ च प्र॒तिष्ठि॑तः । 

तस्य॑ प्र॒कृति॑लीन॒स्य॒ यः॒ पर॑स्स म॒हेश्व॑रः ॥

Meaning: I attach the original Bhashya of Sayanacharya below.

He, who is indicated as OM in the beginning of the Vedas, 

and extolled in the Upanishads, and the One who is found

merged in His own creation and yet is above it all, is Maheshwara!
