You can be healthy whenever you work for goodness. The conscience is God's representative in man. To neglect the conscience is to neglect God. The wrong viewpoint makes everything a problem. Goodness is the true love action directed toward benefiting the whole.
Evil is false action directed toward benefiting the individual.
Good and evil can both be my teacher. Heaven and Hell look the same externally, but internally they are different. The means is for the sake of the purpose. So, if it is used for a bad purpose, the result will be trouble. Living for the sake of the greater rather than the smaller is goodness.
