How Can One Accord with and Enter the Principle?

The five aggregates, the eighteen realms, and the twelve entrances arise from the convergence of various causes and conditions, and they vanish when those causes and conditions disperse. How is one to accord with and realize this principle? The mind consciousness can grasp a rough idea of it simply by thinking about it, yet you yourself also know that this is not genuine understanding; you still need to deeply and definitively comprehend its meaning, with sound reasoning and evidence. This requires that, within meditative concentration (samādhi), you suspend this principle in your mind, letting the manas deliberate upon it single-mindedly, deliberating continuously and meticulously at every moment. The manas's deliberation is hidden, uninterrupted, and unattached to sense objects; it has a certain height and depth—this is called viewing from a high vantage point.
