One of the most fundamental requirements in meditation is restraining the mind. Rather than running out, energy can settle and calm. Then one’s effort is neither straining towards some goal, nor enmeshed in agitation. There’s space for sensitivity, receptivity, listening. When the outflows are restrained goodwill, compassion, clarity and wisdom come forth on their own.
Use the three intelligences of heart, mind and body to create a sense of calm and happiness. Body helps restrain mind; heart generates an atmosphere of gentleness and goodwill. Know what’s worth giving attention to for liberation.
