Sustainability is a popular concept in these times, and that’s a good thing. It appears to me that the primary application of the term is as regards organic farming and gardening. All good again. Sustainability has both broader and deeper meanings, however. Sustainability includes not wasting and not using up. So yes, not depleting the soil is a good example. Another is in the workplace, not just by not wasting paper and such — but by highlighting the benefits of work environments that don’t burn people out. It’s good for everyone, including the organization. Sustainable means supporting people in developing their own creativity and personal development. Our culture will do better when we apply sustainable approaches to all we do.
Spiritual sustainability suggests to me living a life in which each day we do the little things that keep our energy high and our thoughts with God. As Paramhansa Yogananda said: "The minutes are more important than the years."
