Detachment does not mean you own nothing; it means nothing owns you.
– Bhagavad Gita
When we are attached to something we repel other possibilities on our way. Being detached with everything and not be identified with anything is the best possible way to live a happy and extra-ordinary life.
Being attached with something means doing things to get those things, which as a result create ego, hatred, jealousy, argument, and many negative triggers. All of these bring disharmony in our life.
Being aware of it is the most important lesson we have to learn as early as possible, otherwise it’s going to deep-seated within us and hence will be very hard to remove.
