Those who feed their bodies become morons; those who feed their minds become geniuses.
Have you heard or read the proverb genius is 99 percent perspiration and 1 percent inspiration? it means be active with karma and studies to fill the brain cells with information on life and the lessons you learn to develop knowledge. The Mind is the Store-room of knowledge. The more it expands from ones activities the greater the subconscious derives the instinctive reactions to opportunities to better oneself materially in life and avoid dangers so that one can survive for a very long time in the wilderness that is Nature. Otherwise one limits one scope towards prosperity if one simply feeds the belly, wears good clothes, and enjoy music and play sports and such mundane activities. When the mind is restricted from being brainwashed by fixed ideas of one's educational upbringing it is operating like a moronic machine and one lives and exists like a slave to one's human or God masters. Nothing can be more moronic than that.
