Silent meditation (no introduction) starts at 0:18 Questions (25:28): 1. Comment on the concepts of time and space. 2. What role do the “Hidden Lands” play in the context of Buddhist practice? 3. In the Vajrayana, there is the practice of the illusory body. Is there anything like this in the Mahayana? What is the concept of “wilderness” in practice? 4. What is the role of devotion and reverence in practice? 5. Pondering the metaphor of the carriage and the Four Immeasurables being like four horses, I have explored what the other parts of the metaphor are in my own practice. For example, the reins (which must be held not too tight or not too loose) are the discipline of my practice in the hands of the driver—who might be inattentive or alert, a good driver or not so good on any given day. The wheels and undercarriage are the Four Thoughts that Turn the Mind (Precious human existence, Death and Impermanence, the Law of Karma, and the Defects of Samsara). Who is inside the carriage (a passive passenger or a master who knows the destination and the route to it and can keep the driver going in the right direction). Are there other interpretations? A similar metaphor appears in the Upanishads. Is there an expanded metaphor in Buddhist text?
