There are lot of Puranas and Stotras about every God/ Goddess in Hindu religion. This provides liberty to the devotees to imagine the God/ Goddess in the form of his/ her choice. However, when these Puranas and Stotras are studied in depth it is very clear that they all convey the same sense. In one place it is Narayana and in another place it is Narayanee. Somewhere it is as Ardhanareeshvara - i.e. The left half of Sankara is Sreedevee and in another place he is Sankaranarayanan - i.e. Narayana sharing the body - left half with Lord Sankara. Logically this clearly implies that both Shreedevee and Narayana are one and the same. Likewise there are lots of similarities between Stotras about different Gods/ Goddesses. It may not be a surprise that Lalita Sahasranama has similarities with Soundaryalaharee and Saptashatee, because all the three are about Sreedevee. But how about Vishnu Sahasranama and Shremad Bhagavad Geeta. Primarily they are supposed to talk about Lord Vishnu, but still they also talk the same language - about Sreedevee. Hence it can be concluded that there is only one God. Whichever form of God we worship we are in the path to liberation. Devotees can imagine the form of that God in the way they like and worship. Let Sreedevee shower her choicest blessings on the readers. Om Tat Sat
