When phenomena are individually analyzed as selfless, and what has been analyzed is meditated upon, that is the cause for attaining the fruit, nirvana. One does not go to peace through any other cause
Every day, do something selfless for someone else that takes under five minutes. The essence of this thing you do should be that it makes a big difference to the person receiving the gift. Usually these favors take the form of an introduction, reference, feedback, or broadcast on social media. Do something that's not for yourself, every single day. Expect nothing in return. Over time, these random acts of kindness will really add up.
