Can an unmarried man take sanyas ?
Many scriptures say marrying and having a son is compulsory in life. So, one must have a son before taking sansyas , Is it true ?
There is an example of one Jaratkaru in Mahabharata ,who had become ascetic without marrying . Then one day he saw his ancestors falling from heaven to hell . His ancestors told him (Jaratkaru) to marry and have a son first then become ascetic so that their family line don't die otherwise they will fall to hell.
