"It is extremely hard to rest undistracted in the nature of mind, even for a moment, let alone to self-liberate a single thought or emotion as it rises. We often assume that simply because we understand something intellectually, - or think we do - we have actually realised it. This is a great delusion. It requires the maturity that only years of listening, contemplation, reflection, meditation, and sustained practice can ripen."
Sogyal Rinpoche
