Art 28

I will rejoice in Jerusalem, and delight in my people; no more shall the sound of weeping be heard in it, or the cry of distress. No more shall there be in it an infant that lives but a few days or an old person who does not live out a lifetime; for one who dies at a hundred years will be considered a youth, and one who falls short of a hundred will be considered accursed. They shall build houses and inhabit them; they shall plant vineyards and eat their fruit. They shall not build and another inhabit; they shall not plant and another eat; for like the days of a tree shall the days of my people be, and my chosen shall long enjoy the work of their hands. They shall not labor in vain, or bear children for calamity; for they shall be offspring blessed by the Lord— and their descendants as well. (Isaiah 65:19-23)

At the main entrance [of a monastery] you should have a painting of a spirit (yakkha) holding a club; in the veranda representations of the great miracle, the realms of existence, the wheel of birth and death and Jàtakas; at the door of the main shrine a spirit holding a garland; in the hall you should have monks and elders teaching the Dhamma; in the dining room a spirit holding food and at the door or the storeroom a spirit holding an iron hook. At the well you should have paintings of dragons (nàga) with water pots; in the bathroom scenes from the purgatorial realms; in the dispensary the Tathàgàtha nursing the sick; in the toilet depictions of the horrors of the charnel ground and in the sleeping quarters a skeleton, bones and a skull. (Sarvàstivàdin Vinaya)
