Vaishnavas believe that Lord Vishnu is supreme hence they are discouraged from worshipping other gods like Lord Shiva, Ganesha, etc.
But what about the associates of Vishnu like Sudarshana chakra, Garuda, Vishwaksena, etc.? Can they pray to/worship them?
What about acharyas like Ramanujacharya, Vedanta Desika, etc.?
What about living acharyas, elders, etc.?
What about Hanuman?
