Inviting our heart to let go of all reservations and conditions to universal friendliness and kindness. This heart which can hold all beings in kindness becomes a refuge for our own well being and the well being of others.
Continuing from the Anapanasati sutta we turn to vedana, the 2nd foundation of mindfulness. With great courage. we can develop contentment no matter the pleasure, pain or neutrality of any give moment. In not understanding vedana we are forever imprisoned by our wrong views. When we can breath consciously in a greater range of pain, pleasure and neutrality we find the path to non-conditional contentment.
