If you go to
https://narayanastram.org website and fill in your details and register, you will be sent an email with a Ramayana hymn, a Bhagavad Gita hymn and a name from Vishnu Sahasranama. That is called Narayanastram. You must read that Narayanastram at least once a day whenever you can. In fact, the Narayanastram is an instrument to keep with you always by writing these two verses and a name on a piece of paper and should carry like the Aadhaar card or driving license.
