Vigor is to health as tranquility is to what?

Vigor is a state of robust health and energy, indicating strength and vitality. Similarly, tranquility refers to a calm and peaceful state, free from disturbance or agitation. Therefore, the parallel can be drawn that just as vigor relates to health, tranquility relates to peace.

Peace embodies the essence of tranquility as both concepts connote an absence of conflict or disturbance. In a tranquil state, one experiences peace, similarly to how one experiencing vigor enjoys a state of good health. This alignment makes peace the most fitting counterpart to tranquility.
