Krishna teaches us about the different ways of becoming spiritual. Krishna is [an] avatar of Vishnu born on earth to help us understand religion. He teaches how we can think about God in different ways and how we can find God using different methods. He teaches that we are all God's playmates, and are born on earth to take part in God's play. Krishna is shown with his partner Radha. Krishna is sometimes shown holding a flute. His hair is decorated with a peacock feather. Krishna's teachings about religion can be read in a book called the Gita.
