Verse 1
ॐ नमस्ते गणपतये । त्वमेव प्रत्यक्षं तत्त्वमसि । त्वमेव केवलं कर्ताऽसि । त्वमेव केवलं धर्ताऽसि । त्वमेव केवलं हर्ताऽसि । त्वमेव सर्वं खल्विदं ब्रह्मासि । त्वं साक्षाद् आत्माऽसि नित्यम् ॥ १॥

oṃ namaste gaṇapataye । tvameva pratyakṣaṃ tattvamasi । tvameva kevalaṃ kartā'si । tvameva kevalaṃ dhartā'si । tvameva kevalaṃ hartā'si । tvameva sarvaṃ khalvidaṃ brahmāsi । tvaṃ sākṣād ātmā'si nityam ॥ 1॥
