Is it really possible to be always happy when you are enlightened?
Yes. But it’s not the happiness that people are seeking. Not the excitement or euphoria of an achievement. Not the contentment with who you are or how things are, either. It’s peace, serenity.
And the joy of enlightenment is also not the emotional joy, it’s the joy of the body, the joy of the senses. The joy of creativity can also be said to be the joy of the body, because the brain is a part of the body.
