To let someone become a nun or monk, or yourself become a renunciate, the merit is as great as the sky above, as deep and wide as the ocean underneath. The renunciate person uses Buddha’s teaching, sutra, as water to cleanse all his piling-up karma, residues of karma, from life after life. From then he will cut off all these rebirths, deaths, suffering, sickness, etc, etc. And from then on, he uses that as a seed to grow Nirvana, Bodhi Tree. These persons, the renunciates, use precepts, moral precepts, as if his eyes to light his way on his spiritual practice, and he will always walk on the straightway of the real Buddha Dharma, until Nirvana.
