maha ganapatim manasa smarami
vasishta vama devadi vandita
maha deva sutam guruguha nutam
mara koti prakasham shantam
maha kavya naatakaadi priyam
mooshika vahana modhaka priyam
A composition in Natai raga by the legendary eighteenth century composer, Muttuswami Dikshitar, this is a prayer in Sanskrit to Ganesa, Lord of Obstacles, seeking an auspicious beginning to any sincere and good task; any artistic performance is an offering to Him.
Here's KJ Yesudas singing Maha Ganapatim.
I meditate on the supreme Ganapati who is worshipped by
sages like Vasishtha, Vamadeva and others.
He, the son of Lord Mahadeva, is adored by Guruguha and
shines with the brilliance of millions of cupids. He is the tranquil
one and exults in poetry and drama.
He is fond of Modaka (a kind of sweet), and has a mouse for a mount.
Here's Sushila Raman's rendition of Maha Ganapatim.
