Sadhguru
Why does losing a partner leave me feeling so empty, and how do I stop that?
Come to relationships from fullness
We build who we are like a collage, partly out of the people in our lives, so losing one leaves a vacuum in us. Form a relationship because you want to share your fullness, not to make yourself complete, and there will be no grief when you lose somebody.
If you use a relationship to make yourself complete, then when you lose it you become empty. If you form a relationship to share your fullness, there will be no grief when we lose somebody.
