Of the six realms, only in heaven are babies born clothed. In this world, people such as Śānavāsa and Nun Senbyaku emerged from their mothers’ womb fully clothed. This is not only because they had given clothing to revered people, but also because they had the karma of offering pure, thick clothing to their parents, masters and the Three Treasures.

Śānavāsa was born fully clothed because he had once given clothing to a naked Pratyekabuddha. Also Gautami had the virtue of giving gold-embroidered clothing to the Buddha, and according to the Lotus Sūtra she became Issai Shujō Kiken Buddha.

Since you have given clothing to the venerated Lotus Sutra, you will not only avoid the eight hells of ice in the next life, but also avoid hardship in this life. Your overflowing virtue will be given to your sons and daughters, and you will experience joy upon joy, and happiness upon happiness.
