Through countless births in the cycle of existence
I have run, not finding
although seeking the builder of this house;
and again and again I faced the suffering of new birth.
Oh housebuilder! Now you are seen.
You shall not build a house again for me.
All your beams are broken,
the ridgepole is shattered.
The mind has become freed from conditioning:
the end of craving has been reached.
When one drives away the negligent through vigilance, he climbs the heights of wisdom, and can see the suffering masses. Serene, you look upon the lost like one that stands on a mountain sees those that stand upon the plain.
That which goeth up must needs come down; and that which is down must needs go up. But Brahma has ordained that the that that goeth up is seldom the same as the that that hath gone down.
And for a disciple thus freed, in whose heart dwells peace, there is nothing to be added to what has been done, and naught more remains for him to do. Just as a rock of one solid mass remains unshaken by the wind, even so, neither forms, nor sounds, nor odors, nor tastes, nor contacts of any kind, neither the desired, nor the undesired, can cause such an one to waver. Steadfast is his mind, gained is deliverance.
Persevere in thy quest and thou shalt find what thou seekest. Pursue thy aim unswervingly and thou shalt gain victory. Struggle earnestly and thou shalt triumph.
Pain in life is inevitable but suffering is not. Pain is what the world does to you, suffering is what you do to yourself [by the way you think about the 'pain' you receive]. Pain is inevitable, suffering is optional. [You can always be grateful that the pain is not worse in quality, quantity, frequency, duration, etc]
In exactly the same way, ... scatter your body, your feeling, your perception, your predispositions, your discriminative consciousness, break them up, knock them down, cease to play with them, apply yourself to the destruction of craving for them. Verily, ... the extinction of craving is Nirvana.
Peace comes from within. Do not seek it without. It can be argued that peace and happiness comes from the subjective internalised perspective of realizing things could be worse and being grateful they aren't. The alternative view that peace and happiness comes from the objective external perspective of having more and better things than at present, while important for growth, can be a never-ending source of jealousy, dissatisfaction and disappointment. A balance of the two, where people are grateful for what they have while striving for more seems the best blended perspective.
