The more complete and lasting your śamatha, the more strongly developed these factors are, and the more chance there is for Insight to arise. Yet keep in mind, attachment to Insight can itself be an impediment. It’s far better to surrender all hopes and expectations. Just practice from a place of trust, for the sake of whatever your meditation may bring. These Insights will come in their own time. Awakening is an accident, but meditating on the mind is a practice that will make you accident-prone.
