Mahashakti

Hello, I am new here and would appreciate input. I have been privately studying Advanced Tantra in Canada and it is not possible for me to come to India. I am thinking of going for the "Om aravidhe swaha" mantra 27000 times in one sitting facing east. As I am healthy and very familiar with tantric and occult studies in theory and practical I am not so worried about the scare scenarios about this Pishachini. I would like someone's input about this. Thanks
