Glimpses of love and joy or brief moments of deep peace are possible whenever a gap occurs in the stream of thought. For most people, such gaps happen rarely and only accidentally, in moments when the mind is rendered "speechless," sometimes triggered by great beauty, extreme physical exertion, or even great danger. Suddenly, there is inner stillness. And within that stillness there is a subtle but intense joy, there is love, there is peace.
