Who is Vaishnav and what is his duty ?
Purush evedam sarvam yadbhutam yachcha bhavyam .The Vaishnav is he , who changes the cloudy sky of ignorace to the originality of Vishnu as blue .
It is right to say that as per Vedas the character of Vishnu shown resembles the noble one , means neither so ordinarily brave as Indra , nor so destructive as Rudra and of course most suited to be a Vaishnav for human beings .Also aham brahmasmi or tattwamasi , make no proper sense as it is mere prayer. See…Yagne syamaham twam twam va gha sya aham . Syuste satya ihashishah..rig 8/44/23If only the Parabrahma or parmatma is to be prayed, which is one and not the else .It is not me not you and not the anybody, so pray , the Almighty . See….Apra dyava prathavi antarikshim surya atma jagtaststhusashcha….rig 1/115/1So it is not Vishnu , Indra , Rudra etc. etc.
Be Vaishnav, Help the needy as much as , you can .
