Power of mind vs. material wealth

I find discovering and developing the powers of the mind much more pleasant and fruitful than digging for silver and gold. After physical death what we can take with us to the spiritual world is lessons we've learned but none of material things of the physical world. Also spiritual growth brings peace of mind no matter what circumstances are when the biggest material wealth will not protect from one's personal insecurities, doubts and depression. The key to fight and survive any battles in life is to be able to choose how to react to every situation, than it will make us stonger and mentally immune to anything as we go on the journey.
