Enlightenment is the union of wisdom and compassion. It is not advisable to merely pursue wisdom without a strong, constant effort toward cultivating compassion. In fact, efforts should be focused primarily on developing compassion in the initial stages of the path. And we are all beginners!
Excessive (obsessive) preoccupation with our own mental states is unhealthy. It is not conducive to enlightenment. It is a manifestation of self-grasping and self-cherishing, albeit disguised as “spiritual cultivation”.
If we want to make spiritual progress, we must dedicate our time, talents, and treasure to universal benefit. If we want to reduce our self-centeredness, we must help others, serve others: heal the sick, nourish the young, protect the weak. In small or big ways, every day, to help sentient beings, human and non-human, is the best course of action.
“Avoid harm. Do good. Purify the mind. This is the teaching of all the Buddhas,” in THAT order.
This is advice from the heart.
