Avarana krama for Maha prAsada Vidya is different from Srichakra Navavarana and is described in the Krama Tantras. Also, one should understand that the Maha Prasada Vidya does not refer to prAsAda bIjA – parAprAsAda or prAsAda parA, but instead to the 32-lettered vidyA – which is described as avidyAcChedinI or parA chintAmaNi in the Tantras. The AvaraNa procedure for mahA prAsAda, which is given along with mahA pAdukA during pUrNAbhiSheka in dakShiNAchAra sampradayas, is very elaborate and here is a brief description of the same:

The Mahaprasada Avarana has to be worshipped after Urdhwamnaya Puja (i.e. after Urdhwamnaya Shadavaranas) and Adharamnaya Puja and before Anuttaramnaya Puja. Each of the Avarana Devatas should be worshipped with their mula mantras, with the addition of Urdhwamnaya Panchatari. According to Sampradaya, one should start worshipping Shodashavarana of Mahaprasada Murti, after Purnabhisheka, starting with Vyasa Pournami, after performing Gurumandala and Shadanvaya Shambhavi Yajana. One should conclude the pUja with Rajarajeshwara Bali. The practical details should be learnt from one's Guru. Though some use mahAprAsAda yantra, all Srividya Upasakas should perform the pUjA in Srichakra itself, visualizing the sixteen Avaranas as described in Kubjika Tantra. These details have been posted here, only to share information. This is the Paddhati followed originally by priests of Pashupatinath Temple in Nepal, later learnt by Brahmanas in the south [Chidambaram].
