Lord Vishnu is one of the Trinity of Gods. He is the destroyer of all the sufferings in the Universe, powerful, and the illuminator of all three realms. He resides in Vaikuntha and the Kshir Sagar as the Lord of Sri. Whenever there is a decline in righteousness on Earth, Vishnu incarnates to restore it.
 
Vishnu Chalisa contains a beautiful hymn praising Lord Vishnu in one couplet and forty verses. Reciting Vishnu Chalisa brings an increase in happiness and prosperity. Through the grace of Lord Vishnu, one attains success, intellect, wealth, strength, and wisdom
