Punya and Paap are the seeds of future pleasure and pain, the former, which sows merits, exhausts itself only through pleasure and the latter, which sows demerits, exhausts itself only through pain; but liberation from rebirth is the end of all karmic debts consisting of and signified by these two dynamics.
In the chapter 5 & 6 in Section 5 of Uma-saṃhita of Shiva Purana and in discourse 11, section – 6 of Manu Smriti, different types of sins are enumerated.
There are twelve types of Maha-Paap:
The following six are the great sins attended with endless evil results, viz: —censure of Shiva, censure of the preceptor, censure of Shiva’s perfect knowledge, misappropriation of the wealth of the lord, destruction of the wealth of brahmins and the foolish stealing of the sacred text of Shiva’s perfect knowledge.
Those who do not take delight on seeing a well-arranged worship of Shiva, who do not bow to or eulogise it on seeing his phallic image that is worshipped, those who do not scrub, clean and sanctify the spot of worship during festival days; those who do not duly cooperate with the preceptor in their sacred rites; those who misbehave as they please, play about mischievously and do not render service in front of Shiva or in the presence of the preceptor; those who eschew Parvati course of conduct and discipline, those who hate Shiva’s devotees; those who begin to study or write about Shiva’s knowledge without worshipping; those who give without justice or justification; those who listen or recite indiscriminately; those who sport about covetously; those who pursue false knowledge or do not have proper rules and regulations; those who lie down and sleep in dirty uncleaned spots; he who abuses Śiva’s story and knowledge and begins to expatiate on other things; he who does not speak the truth; he who does not make gifts; he who is bodily impure and begins to explain or listen to Shiva’s story in an unclean place; he who begins to listen without worshipping the preceptor; he who does not render service to him or pay heed to his behests with devotion; he who does not support the preceptor’s statement; he who retorts to his preceptor; he who conveniently ignores the most difficult task of his preceptor; he who deserts his preceptor when he is in distress, or when he is unable to maintain the disciple, or when he has gone abroad or when he is attacked by enemies; he who treats with contempt the teacher of virtuous activities and ability to discourse; he who disrespects the teacher’s wife, son or friends.
The murderer of a brahmin, the addict to wine, the habitual thief, the defiler of the preceptor’s bed and he who associates with these is the great sinner fifth in all.
