When this delusion of utter separateness underlies and governs whatever I think, say, and do, what kind of world do I create?

The word 'heart' can refer to an emotional bond between people, and also to the precious faculty of empathy, an 'open heart', which means sharing the feelings of another and includes an outflow of goodwill towards our fellow humans and all life forms. This, of course, is what the Dalai Lama refers to when he says "my religion is kindness", and is closely related to the ability to feel compassion.

The truth is: you don’t have a life, you are life.

You don't need to condemn. Just observe, That is sin. That is insanity. That is unconsciousness. Above all, don't forget to observe your own mind. Seek out the root of the insanity there.

Forgive yourself for not being at peace.

You become most powerful in whatever you do if the action is performed for its own sake rather than as a means to protect, enhance, or conform to your role identity.

To be conscious of Being, you need to reclaim consciousness from the mind. This is one of the most essential tasks on your spiritual journey.
