The Manusmriti 2.112 says:
धर्मार्थौ यत्र न स्यातां शुश्रूषा वाऽपि तद्विधा । तत्र विद्या न वप्तव्या शुभं बीजमिवौषरे ॥ ११२ ॥
Where merit and wealth are not possible, nor is there an adequate desire to serve, there knowledge should not be imparted; just as healthy seed (is not sown) on barren land.—(112)
Also the same goes with imparting knowledge to ignorant people and non-believers.
Question:
- What all happens when one imparts knowledge to forbidden categories of people?
(One verse in the Manusmriti says that such a person goes to Naraka. Besides that what are the other effects? Like some say, one forgets such knowledge, etc.) - Does the same apply in case of inadvertently reciting the knowledge and someone unfit hearing it?
- What is the prayashchitta one can do in case such a blunder has been committed?
Any source Pauranika smarta tantrika Vedic will be acceptable, but please list out all the effects.
