Ice fishing is meditative itself, you have to be ready for fish attack, and it will sometimes take a time. During fishing we teach how to clear your thoughts with mindfulness methods. There is a nice contrast from zen to adrenaline rush, when fish attack.
Spring winter is best time for that, ice is strong enough and the sun already warms you. After time on ice it is nice to go heat up chaga mushroom tea on campfire. That gives you a detoxifying superpower just before summer.
