Lama Yeshe says : “So in order to develop universal love and compassion, you need to feel equanimity with all living beings. This makes your mind very healthy. Lord Buddha himself said that you should not be attached to anything, not even the realization of enlightenment. If you are, then when somebody says there’s no such thing as enlightenment you freak out. That’s Your problem.
Often when you’re attracted to a certain religion or spiritual philosophy you immediately exaggerate it’s good qualities and grasp at it, thinking, ‘oh this is fantastic this is so good…’ This can be very dangerous, because when somebody says that your religion is no good you freak out. That’s the unhealthy mind at work. Irrespective of the religion, philosophy, psychology or whatever else you follow, if somebody says it’s no good you get upset. That’s Your problem.
Therefore Lord Buddha said that we should not be attached to even the concept of higher realisations and enlightenment let alone sense objects.”
