Detachment is not dispassion nor is it indifference. It is also not an absence of love.
In fact, it takes great love to be detached. In its deepest form, love can only be detached. You need great love to show great
To care for one person is usually attachment-driven but to care for the world, you can only be in a state of detachment.
Detachment can never be dispassion. It is compassion, filled with an inner well-spring of caring.
Compassion as personified by great souls throughout history is nether pity nor sympathy. Nor is it empathy or is it kindness.
It is love... driven by understanding. It is without precondition or expectation.
It dwells in detachment. It alone has changed the coarse of human history. As it still does.
