To advance spiritually requires a method of practice & determination to carry it out.
Any methodology for developing patience requires a multi-tiered approach.
That's why it's called a practice. We have to practice a practice if it is to be of value.
The more we genuinely care about others the greater our own happiness & inner peace.
So what is a good meditator? The one who meditates.
Accepting the reality of change gives rise to equanimity.
