But, this mantra that you have posted is combination of all these three mantras which is what made me amazed, showing the merging of all forms and mool mantras and took me here to your blog to enlighten me the essence of Advaita as Supreme soul is above all forms and limitations. Just wanted to inform you that, I have already been initiated to Maha Gaṇapati, Sri Saubhāgya Pañcadaśī and Gāyatrī maha mantras, all separately. I will wait for the reply of yours with Vidi of Śrī Vidyā Gaṇapati Vāñcha kalpalatā mantra with Rishi, Nyasa and Dhyana Sholka. There are other variations of this mantra as well, like adding the first verse of Durga sūkta, Bālā mantra, etc.

(Dictionary meaning of kalpalatā – a creeper that grants all desires) This is the Ganapati Vancha Kalpalatha Mantra: Vāñcha means wishing or the one who desires for something and kalpalatā means granting all desires. This mantra is a combination of mantras of Gaṇapati, Saubhāgya Panchadaśī and Gāyatrī. Śrī Vidyā Gaṇapati Vāñcha kalpalatā mantra
