In the teachings of the Kurma Purana, the sages set forth the sacred guidelines for purification after the passing of loved ones, so that the living may return to their daily lives in harmony with dharma. They explain that, if one so desires, a ritual bath may be performed a year after a death, marking a final act of purification. Yet, in some circumstances, purification is immediate—there is no waiting, no prescribed period of impurity, and this applies at all times and in all situations where it is warranted. For those relatives who share the same ritual offerings—such as a wife participating in her husband’s rites—the period of impurity is set at three nights. However, if a child passes away before reaching two years of age, the tradition declares that purification is immediate; there is no period of mourning to be observed. When a daughter is given in marriage, or if she dies while still in her father’s house, the father’s period of impurity lasts three nights. Similarly, when a gift is given, a period of three nights is observed; if the time is exceeded, the period extends to ten nights. This same rule applies to impurity arising from death or birth among those who share the same water, signifying close communal ties. For teachers and fellow students, the prescribed period is one night. For one’s own wives, for a teacher, and for other women, the period of impurity is three nights. When it comes to a sub-teacher or a learned Brahmin residing in one’s own village, only one day is required. If the wife is not the chosen one, the period is just one day, or even one night. When a kinsman of the same lineage dies, immediate purification is prescribed. As for the different social classes, a Vaiśya becomes purified after fifteen days, while a Śūdra requires a month. Among all, a Brāhmaṇa is considered purified after ten days of impurity. Each person should observe the period of impurity appropriate for their own class and lineage, in accordance with the rules—this is the path to purification, and there should be no doubt about it. The scriptures further state that impurity arises for Vaiśyas, Kṣatriyas, and Brāhmaṇas through contact with Śūdras; for Śūdras, Kṣatriyas, and Brāhmaṇas, impurity arises from contact with Vaiśyas. In the case of a Kṣatriya, the period of impurity is also specified, and the lotus-born Brahmā declares that purification is attained in ten nights. If one has eaten or dwelled together with the deceased, purification is achieved in ten nights. On the day of death, one should neither eat food nor remain in that house. If a sapiṇḍa relative (a close kin sharing ritual offerings) touches a corpse, they are purified after ten days. For the twice-born, ten days are required; for a king, twelve days. Alternatively, purification may be attained by all in six nights, or even in three nights, depending on the circumstances. After bathing and partaking of ghee, Brāhmaṇas and others become purified. If, out of affection, one touches another during the period of impurity, the same period of impurity must be observed for purification. Bathing with clothes on, touching fire, and partaking of ghee are also means to become purified. For a Śūdra, three days are prescribed, or, alternatively, one may perform a hundred breath-control exercises. The period of impurity may be three nights, or, in some cases, just one day. For a Brahmin, sometimes only bathing is required, especially when performed with light. Indeed, purification can be achieved solely by bathing, even if one remains clothed—there is no doubt about this. Whether the deceased is a relative or another person, ten days is the standard period for purification. When this period ends, a ritual bath restores purity. The impurity lasts for as many days as prescribed, and after that, one should perform acts of expiation. These rules apply in the case of the death of sapiṇḍa relatives and in other deaths as well. The relationship of those who share the same water is determined by knowledge of their birth names. Sapiṇḍa relationships—those who partake of touch and share the self—extend to seven generations. For married women, the ancient deity Pitāmaha declared that the sapiṇḍa relationship is through the husband. For those of different castes, this relationship extends up to three generations. Thus, the sages carefully lay out the path of purification, so that the living may honor the departed and return to their duties with hearts and homes cleansed, in keeping with the eternal laws.
