Munder v. State (Explanation Needed)

Munder v. State is a concept in section 300 IPC but textbooks explain it like it's a math formula. I mean, I've got better things to do than mug up definitions, jab tum log mock tests dete ho, I'm at my shift. Can anyone explain how Munder v. State helps us understand what constitutes murder vs culpable homicide not amounting to murder? Like a real-life example or something? Help!
