Penang Retreat 2019 Group 4 Round 4 (1:01:31-1:02:45)
Metta is loving-kindness – it is a wholesome mind, and all wholesome minds are calm. It is wishing others to be in a better situation; it is also the opposite of dosa.
Metta is also good for you because you are generating a wholesome mind.
Dosa wants to destroy; metta wishes others to get better and better.
