“The choice for mankind lies between freedom and happiness and for the great bulk of mankind, happiness is better.”

Simplified Meaning:

People have to decide between being free and being happy, and most people think being happy is more important. Imagine you have a job that makes you feel safe and content, but you can't choose what to do or how to do it. You're given everything you need, but you have no control over your decisions. For example, in some countries, people live under strict rules but are provided with basic needs and security. They do not have the freedom to make their own choices, but many feel happy because their needs are met. The quote suggests that for most people, having their basic needs satisfied and feeling secure is more valuable than having the freedom to do whatever they want. So, in your own life, you might think about whether you're more content with a predictable and stable life or if you would prefer the freedom to make all your own choices, even if it means facing more risks and uncertainties.
