I loved this cite very much, did not expect to find it out in the 4th Chapter of "Shree Bhagavad-Gita" (page 234 in the following Edition - "BHAGAVAD-GITA (VYAKHYAMRTASARITA)", HINDI, Ramanuja Sampradaya - http://vishnudut1926.blogspot.ru/2013/06/bhagavad-gita-vyakhyamrtasarita-hindi.html)
The only Pramana which exists for me is just "Shree Lakshmi-Tantra", the Only Adored Goddess is Shreemati Lakshmi-Devi
