The Lord Maha Vishnu is the preservator fo the world and he is a part of Lord Shiva. According to the "VEDAAS" the best way to get the bleassings of Lord Mahavishnu and Lord Shiva simultaneously is performing pooja to the Chalagramam. Chalagramam is a kind of special stone which is naturally shaped by the falling water from the hills, and it is very hard to procure the apt pieces according to "Vedaas" and "Sastraas" and we have procured the pieces with utmost care and under the guidance of learned Pandits and Intellectural Giants.
