Emotions should be streamlined through wisdom. When there is wisdom then you know which emotion to express and which not to express. And where you should express, and where you should not.
Enlightenment is getting in touch with the buddha inside us.
The formula is:
1. Having clarity in mind, purity in heart, and sincerity in action.
2. Keeping a smile and doing meditation.
3. Seeing life from a bigger perspective.
