Mokshopaya is a really fancy and complicated word that comes from a religion called Hinduism. It means "the way to achieve liberation from the cycle of birth and death."
So, let's break that down. When someone is born, they live their life and then when they die, they are born again as a new person. This is called the "cycle of birth and death."
But sometimes, people in Hinduism don't want to keep being born again and again. They want to be free from that cycle and live forever without having to start over as a new person. This is called "liberation" or "moksha."
Mokshopaya is the way to get to that liberation. It involves following lots of rules and being really good in your life. Some people believe that you can also get to moksha by meditating or praying.
Overall, mokshopaya is a way for people who follow Hinduism to try to move on from being born and dying all the time, and instead live forever in peace.
