Judaism doesn't have monasteries, monks and nuns. We don't have Gurus in isolated mountain retreats, either. We marry and have children.
We don't sleep on beds of nails or flagellate ourselves. We enjoy our lives, every minute of the day.
Jewish law demands cleanliness and presentability, so we don't walk around in rags.
Those who truly adhere to Jewish Law eat well, dress in a dignified manner, exercise and guard both physical and spiritual health. We use every part of our body in the service of Hashem; that way, we uplift the physical aspect of ourselves and transform it into sublime spirituality. Our bodies are therefore subservient to our souls. How?
We cling to Hashem with emuna, pure and simple faith. Emuna overrides intellect. Why?
Intellect tells you to worry; emuna says there's no reason ever to worry. Intellect tells you to be sad; emuna says there's no reason ever to be sad.
Emuna is truly the best of both worlds.
