In the ancient wisdom of the Kuśika Purāṇa, the rules of purification following birth and death are carefully laid out, guiding families through their times of sorrow and renewal. After bathing, all may be touched, except for the mother who remains impure for ten days. The duration of impurity varies: sometimes it is equal to the period itself, sometimes twice or thrice as long, or even four, three, or just one day, depending on circumstance. On the fourth day, Manu, the lord of creatures, has permitted contact with those affected. Yet, for those who disregard these customs and act as they wish, impurity from death may linger until their own passing. Before the sacred initiation rites, impurity lasts for three nights; after the rites, it extends to ten days. For someone entirely without sacred marks, purity is regained in three nights. If a child’s teeth have erupted and both parent and child lack sacred marks, impurity lasts three nights. Among family members who have undergone the upanayana, three nights of impurity are prescribed. The mother’s impurity remains as stated, but the father may be touched. After ten days, if a brother is without sacred marks, his impurity lasts only one day. For those without sacred marks, after changing clothes, three nights of impurity are observed. If all members of the same family lack sacred marks, impurity lasts for one night. For those who do possess sacred marks, the period following is irregular. For women, the duration of impurity is counted in days equal to the number of months. Immediate purification is prescribed for relatives who share the same oblations and in cases of miscarriage. For a kinsman who follows his own wishes, three nights are prescribed. For others, purification is achieved in a single day; in remaining cases, it lasts three nights. If impurity arises from the death of one burdened with accumulated sin, it is removed by the subsequent rite. Such impurity can also be purified by the previous rite. A mortal remains impure until the final rites are completed. After a death, bathing is prescribed after a year, if desired, yet immediate purification applies at all times and in all circumstances. For relatives sharing the same oblations, three nights are observed, but only for the husband’s rites. If a death occurs before the age of two, immediate purification is declared. From the time of a gift, impurity lasts three nights; beyond that, it extends to ten nights. The same rule applies for impurity due to death or birth among those who share the same water. For a teacher and a fellow student, one night is prescribed. When a daughter is given in marriage or passes away in the house, the father’s impurity lasts three nights. For a teacher, one’s own wives, and other women, three nights are observed. For a sub-teacher or a learned Brahmin in one’s own village, impurity lasts one day. For a non-chosen wife, one day or one night is prescribed. Immediate purification is prescribed when a kinsman of the same lineage dies. A Vaiśya becomes purified in fifteen days, a Śūdra in a month. Among them, a Brāhmaṇa is purified after ten days of impurity. Each should observe this period for the sake of purification, without doubt, following the rule for their own class and lineage. For Vaiśyas, Kṣatriyas, and Brāhmaṇas, impurity arises from contact with Śūdras. For Śūdras, Kṣatriyas, and Brāhmaṇas, impurity arises from contact with Vaiśyas. In the case of a Kṣatriya, the prescribed period of impurity is given in due order. Ultimately, purification is attained in ten nights, as declared by Brahmā, the lotus-born. Thus, these sacred guidelines ensure that each family and individual observes the proper rites, maintaining purity and honoring the cycles of life and death within the community.
