Then Phralaong says to himself: "The knowledge of the four great truths is the true light that can dispel ignorance and procure the real science, whereby the coming out from the whirlpool of existences, or from the state of illusion, can be perfectly effected. These four truths are: 1, The miseries of existence; 2, The cause productive of misery, which is the desire, ever-renewed, of satisfying oneself without being able ever to secure that end; 3, The destruction of that desire, or the estranging oneself from it, is the important affair deserving the most serious attention; 4, The means of obtaining the individual annihilation of that desire is supplied solely by the four Meggas, or highways, leading to perfection. But these Meggas can be followed only by those who have a right intention, a right will, and who, throughout life, exert themselves to regulate their action, conduct, language, thought, and meditations." It was then that the heart of Phralaong acquired an unshakable firmness, a perfect purity or exemption from all passions, an unutterable meekness, and a strong feeling of tender compassion towards all beings. When these fundamental truths had been known, felt, and relished,[9] Phralaong's mind, casting a glance over the past, was able to discover at once all that had taken place during the countless states of his former existences. He recollected the name he had borne, those of his parents, the places he had seen and visited, the caste he had belonged to, and all the chief events that had marked the course of his progress through the continual migrations. He likewise saw reflected, as in a mirror, the former conditions of existence of all other beings. The immense development and expansion of his mind, which enabled him to fathom the depth of the past, happened during the first watch of the night. He applied now all the expanded powers of his incomparable mind to take a correct survey of all the beings now in existence. He glanced over all those that were in hell, and the other three states of punishment, those living on earth, and those dwelling in the twenty-six superior seats. He at once understood distinctly their state, condition, merits, demerits, and all that appertained to their physical and moral constitutive parts. This labour occupied his mind up to midnight.
