Spiritual health: do I know what gives me strength, can I trust life, can I trust humanity, can I connect with a larger and broader world, bigger than my mind can oversee, and comprehend, do I see myself as part of a bigger union, can I connect with sources of life energy, without loosing myself in a runaway spiritual flightpath, can I find a good balance between myself and everything that is outside me, do I strife for peace, and a greater cause of goodness, are my values morally constructive for goodness larger than myself
Mental health: do I know the difference between things I believe , my own interpretation of what I see, hear, read,… and reality. Do I know the difference between fiction , fantasy and reality, do I know what I dream of, can I make logic connections between thoughts, can I handle my mind?
