More stuff won’t heal your emptiness: The metaphysical cannot be filled by the physical.

The metaphysical cannot be filled by the physical.

In other words, if you feel empty inside, doing/getting physical things will not help you, they will not make you feel better.

You need to find meaning and purpose.

This is just like how you can’t think your way to a full stomach, or hydrated body. You need to satiate the physical need with a physical solution.

So too you cannot physical your way to a fulfilled soul. You must do the spiritual/meaning/purpose activity to fullfill it.
