Eighty-two: [Entering the palace of] an anointed kṣatriya king before the night has cleared and before the jewels have been put away, and so forth, is a pāyattika, except for a great cause.
King Prasenajit had deep faith in the Buddhadharma and ordered his consorts to invite the Buddha individually to enter the palace and receive the teaching. Kālodayin was the teacher of Queen Mallikā. On one occasion, he entered the royal palace early in the morning. The king had already gone out, but the queen had not yet risen. As she moved forward and backward, the jewelled garments she wore were thin and luminous, completely transparent so that her body was revealed on the outside. Seeing her master, she felt ashamed and knelt respectfully on the couch. Kālodayin was also greatly abashed; he immediately returned to the saṃgha and reported the above matter in full. The Buddha said: "A monk entering a king's house incurs two kinds of faults." Because of this, he formulated the precept, no longer permitting them to enter. Kṣatriyas, brāhmaṇas, and householders can all become kings. When a king accedes to the throne, water from the four seas is taken to anoint his head; hence he is called an "anointed king". "The gate threshold" means a limiting wooden beam erected in front of the palace gate. "Before the night has cleared" has two meanings in foreign speech: first, that it is not yet dawn; second, that the queen has not yet risen. If the king and the queen have not yet emerged and the jewelled garments are not yet put away, a monk who steps inside the limiting wooden beam incurs a pāyattika. If the king and queen have both emerged and the jewelled garments have been put away, to enter is not an offense. Later, the consort of King Udayana wished to invite the Buddha and the saṃgha to enter the palace for an offering. Knowing that the precept had already been formulated, the saṃgha would certainly not accept. The consorts together urged and persuaded the king, and the king could not refuse. He made a mobile pavilion to invite the saṃgha; outside the palace, he immediately ordered the wheeled palace to turn away, and the saṃgha blocked its path of approach. The king, knowing that the saṃgha had finished eating, ordered the consorts to present their precious items individually. Then he said to the saṃgha: "Virtuous Ones, you may leave." The saṃgha said: "The Buddha formulated a rule that one must not enter a royal palace." The king said: "I now order you to enter the palace." At that time, the saṃgha recited verses of blessing and departed. Because of this, it was further permitted that when there is a great cause, one may enter. If invited by a king, a king's consort, the crown prince, or powerful high ministers, entering is not an offense.
