When you reach the core that comes after allowing everything to drop, you are naturally cracked open. There is a spiritual heart in that core. You uncover not only the emptiness of the radiant mind, but the radiance and warmth of the spiritual heart as well. When you’re really resting, you can actually feel the radiant, empty mind – not as a thought, but as the radiant emptiness of yourself, the nothingness of yourself and of all selves. You also experience the radiant heart fullness and realize that the emptiness isn’t just a bland emptiness – it is heart-full. When the emptiness awakens, you know that it is also the compassionate heart. The warmth of your own spiritual heart comes alive. – Adyashanti
