On Tranquillity of Mind

"On Tranquillity of Mind" by Seneca is a work of Stoic philosophy about the search for inner calm and how a person can face the worries, uncertainties and turmoil of life.

Seneca reflects on anxiety, dissatisfaction, fear, excessive desires and everyday worries, stressing the importance of a balanced life guided by reason. He argues that calm does not depend only on external circumstances, but also on the way we experience and interpret them.

The book encourages readers to work on themselves, to distinguish what they can control from what they cannot, and to build a healthier relationship with desires, losses and difficulties.
