In Hinduism, we went into a lot of rituals and customs; he said there is no need for all these.
Killing animals for sacrifice should not be done. No need for yagyas. Thus he took people from that state to the state of meditation. Buddha spoke about meditation.
In Buddhism, it is said that let everyone be happy, let all the Gods take care of us. It is the same that is said in the Upanishads.
