Meaning
The verse addresses Ganesha directly: one with the curved trunk and vast body, whose radiance equals ten million suns. Nirvighnam kuru me deva asks him to make the devotee's work free of obstruction, sarvakaryeshu sarvada, in all undertakings and at all times. Sanskrit texts and ritual manuals open with this shloka, so it functions as an invocation rather than a private prayer.
वक्रतुण्ड, महाकाय, सूर्यकोटि के समान तेज वाले, सर्व कार्य निर्विघ्न करें।
