Answer:
The journey to the afterlife was long, and so Egyptians were buried with food, water and wine to help them on their travels. ... Beautiful jewellery and clothes were buried with a Pharaoh so they could travel in style to the afterlife.
The ancient Egyptians believed that to enter your afterlife, your heart had to be light. You gained a light heart by doing many good deeds during your lifetime. After you died, on your way to your afterlife, you had to travel through the Hall of Maat. The god Anubis weighed your heart. If the heart was as light as the feather, the person would be able to move to the afterlife. If the persons heart was heavier than the feather, they would be sent to the Underworld or Ammut would eat them.
