Meaning of this slogam - Maha Ganapathim

Sometimes, we will be hearing a silent humming from ourselves and we will not know, how and where we got stuck with that tune....I encountered with one such silent hum when I was entering into my office... It was this song and slogam of "Maha Ganapathim" from Sindu Bairavi

Suddenly there was an urge on me to know and understand the complete lyrics and meaning.... here is what I found... from google

[TRANSLATION]

I meditate on the supreme GaNapati who is worshipped by sages like VasishTha, vaamadEva and others. He, the son of Lord MahaadEva, is adored by Guruguha and shines with the brilliance of crores of Cupids. He is the tranquil one and exults in the literary pieces like poems and dramas. He is fond of Modaka, a variety of sweet, and has a mouse for a mount.

I have been singing this without knowing the meaning .... Thanks to Google :D
