The root cause of all attachment is lack of love.
- Sri Bhagavan
Love is letting go... allowing the other to be himself or herself. It’s not controlling or manipulating. The happiness of the other is important for you, more than yours. That’s Love. When you are controlling, manipulating, demanding, dominating the other... when you have expectations from the other & these expectations affect your relationship with each other, that we call attachment.
As long as you haven’t discovered this Love, attained inner freedom & sharing the same with the other, till then you are only attached. Detachment & Love can be together. But not attachment. You can show love yet stay detached. That’s the beauty of life.
