Hindus believe in reincarnation so how is it possible for a 'medium' to communicate with the departed?

Hindus believe in reincarnation, which posits that the soul is reborn into a new body after death. However, mediums are thought to communicate with the departed soul's essence or consciousness that may linger in the spiritual realm, rather than the physical form. This interaction can be seen as tapping into the spiritual energy or memories of the deceased, which may persist even as the soul transitions to a new life. Thus, the practice of mediumship can coexist with beliefs in reincarnation, as it focuses on the spiritual connection rather than the physical existence of the departed.
