How can we avoid the pitfalls that Mara sets for us on the path? Develop Sati (mindfulness) to act as a gatekeeper that can recognize the earliest signs of delusion, ill will, and greed. At the same time, cultivate paññā, wisdom and sharp discernment to protect against unskillful speech, conduct, and intention or thought. These foundational practices will be both refuge and rescue from the snares of Mara!
