This is the yoga sutra:
By cultivating attitudes of friendliness towards the happy, compassion for the unhappy, delight in the virtuous and disregard toward the wicked, the mind stuff retains its undisturbed calmness.
Before we get into the deeper meaning of the sutra, can we just address the phrase "mind stuff"? I love it. Instead of saying, "My brain hurts," from now on, I'm going to say, "My mind stuff hurts."
Anyway! If we follow Patanjali, does that mean we can really just ignore people who are wicked? I mean, I have an EVIL boss. So when She-Devil calls me into her office, I'm going to ignore her from now on. Then my mind stuff will always be calm.
A good plan for inner peace, but probably a bad plan for keeping my job.
