The topic of reincarnation may be hard for some people to grasp, so I have created the chart below, which depicts the start of the Samsara then the lowest life forms you can potentially be and the highest. You move up a rank if you lived a life full of good karma, if you did evil deeds in during your life when you die you are demoted to a lower life form.
What You Should Have Learned:
Hindu cosmology works in long cycles.
Samasara is the Wheel of Rebirth.
Hindus believe after you die you are reincarnated
Karma is the deeds or actions of a person
Karma is what determines what you will be reincarnated as
If you lived a life full of good Karma you will be moved up the Samsara
If you committed evil crimes in a past life you will be demoted down the Samara
Atman is the real self
