Karmapa on Ecology

The Kagyü lineage emphasizes practice rather than study—of course they go together but the point is to meditate, meditate, meditate. Here's Orgyen Trinley Dorje, the Karmapa, the head of the lineage, talking about ecology:

Discussing the tremendous kindness of others, the Gyalwang Karmapa extended the previous days’ presentation to include all the kindness we receive from the natural environment as well. His Holiness pointed out that every single breath we inhale is the product of countless anterior causes and conditions coming together. We are the beneficiaries not just of a single lungful of the oxygen that is essential to our survival, but of a continual supply throughout our lives. The Gyalwang Karmapa then went on to relate a personal experience he had while circumambulating Gyuto some time back, in which he felt the enormity of all that nature is offering us at all times, and was filled with a sense of wonder at this fact, and with wellbeing and happiness. Often, the Gyalwang Karmapa commented, we focus on all our personal goals and projects, and on what we have failed to accomplish with our own efforts, rather than opening our perspective to the tremendous richness and goodness that nature is offering us at all times, with no effort whatsoever. Maintaining an awareness of this ever-available goodness could bring far greater contentment and joy to our lives.
