People tend to plan their dharma practice, and especially like to dream of making a long retreat. We plan how the retreat hut should look, its shape and where it should be positioned; we plan the time to start our retreat, maybe one, two or three years from now. It is very easy to make such plans, but it is more difficult for these plans to become reality. Therefore it is more realistic to engage in Dharma practice today, right this moment, not tomorrow or next year. Practice now in whatever situation is at hand. Otherwise, your life can easily run out while planning to practice later. Do not make long-term plans.
