Sahasranama stotram
Sahasranama stotram : Shri Vishnu Sahasranama Stotram (Moolmatram), Sri Lalitha Sahasranama Stotram. The word Sahasra means1000 names (wherein 'Sahasra' means thousand and 'nama' means name) - thousand names of a God. The benefits of chanting the 1000 names are numerous and the most important benefit is the liberation of the soul from all forms of bondage and merging with the Paramatma.
What is the difference in chanting Sahasranamavali instead of Sahasranama.
When you chant one thousand names of the Divine, continuously, without prefixing 'OM’, it is termed as 'Sahasranama’ (for example, the audio Vishnu Sahasranama rendered by Smt MS Subbulakshmi), whereas if we chant each of the 1000 names by prefixing with 'OM’ and ending with 'NAMAHA’, then it is termed as SAHSRANAMAVALI! (for example: Om Shree Vishnuve Namaha, Om Dayanidhiye Namaha). Sahsranamavali is ideal when you perform an Archana (offering flowers, bilva leaf, tulasi leaf, etc at the end of recitation of each Nama) for the Lord.
