We recognise it before emotions have set in and also after they have disappeared. We are so used to implying that this or that destroys our peace of mind that we have come to assume that peace of mind is a contrived state that can be arrived at or deleted at will. But this is not the case. Peace and tranquillity are part and parcel of our own mental make up. If they are destroyed during emotional upheavals, our minds might as well be destroyed too.
Peace is the essence of our own innate nature and can never be destroyed.
Peace is with us every single moment of our life, but we do not recognise it. This is because we are ignorant about peace - most of the time we are too preoccupied with the external world and our own running thoughts and emotions to be aware of it. We have lost touch with our inner selves, with what is the best in us. We frantically try to find the answer outside when all the time peace is sitting there, silently waiting until we come home to it.
