From my recent (not very controversial) it gives rise to this thought. We have to understand the difference between good and pad pain. We have to learn to discipline our needs and weaknesses without damaging ourselves.
Discipline to make us physically, emotionally and mentally stronger is the reason we train. To permanently damage ourselves in any way is stupid. Those extra punches, kicks, push ups, minutes in stances etc push us safely beyond our limits, to go an hour without a drink will hardly damage us.
I’m currently fasting for 18 hours a day, I feel hungry, it hurts, but my nausea and stomach tenderness has gone, pain is down 50%, I’ve lost excess weight, my head is clearer and I sleep better. Disciplining my desires and hunger is paying dividends. Sometimes it’s difficult to meditate or train, but discipline means that I realise that these are the days I gain most.
Good pain makes you stronger and able to discipline your desires and addictions, bad pain is when you disregard your own safety and permanently damage yourself.
Know the difference.
