All conditions of this world have the nature to change: the earth, weather, governments, work, health, leisure, family, friendships and so forth. We observe these variations and consider the most critical change of all. It promises the greatest blessing – but first we must plow the interior field of goodness that yields our heart's deliverance. Faithfully, patiently, as we clear away the dust in the mind, the hindrances of greed, ill-will, fear and delusion fall away, and we abide in the clarity, serenity, and joy of the Dhamma. A retreat talk given at Spirit Rock, June 2013.
