Dakṣa Curses Lord Śiva
71
TRANSLATION
One who takes a vow to satisfy Lord Śiva or who follows such principles will certainly become an atheist and be diverted from transcendental scriptural injunctions.
PURPORT
It is sometimes seen that devotees of Lord Śiva imitate the characteristics of Lord Śiva. For example, Lord Śiva drank an ocean of poison, so some of the followers of Lord Śiva imitate him and try to take intoxicants like  gāñjā  (marijuana). Here the curse is that if someone follows such principles he must become an infidel and turn against the principles of Vedic regulation. It is said that such devotees of Lord Śiva will be  sac-chāstra-paripanthinaḥ , which means opposed to the conclusion of  śāstra , or scripture. This is confirmed in the  Padma Purāṇa  also. Lord Śiva was ordered by the Supreme Personality of Godhead to preach the impersonal or Māyāvādī philosophy for a particular purpose, just as Lord Buddha preached the philosophy of voidness for particular purposes mentioned in the  śāstras .
Sometimes it is necessary to preach a philosophical doctrine which is against the Vedic conclusion. In the  Śiva Purāṇa  it is stated that Lord Śiva said to Pārvatī that in the Kali-yuga in the body of a  brāhmaṇa  he would preach the Māyāvādī philosophy. Thus generally it is found that the worshipers of Lord Śiva are Māyāvādī followers. Lord Śiva himself says,  māyāvādam asac-chāstram. Asat-śāstra , as explained here, means the doctrine of Māyāvādī impersonalism, or becoming one with the Supreme. Bhṛgu Muni cursed that persons who worshiped Lord Śiva would become followers of this Māyāvādī  asat-śāstra . It is called  asat-śāstra  because the Māyāvādī doctrine attempts to establish that the Supreme Personality of Godhead is impersonal. Besides that, among the worshipers of Lord Śiva there is a section who live a devilish life.  Śrīmad-Bhāgavatam  and  Nārada-pañcarātra  are authorized scriptures that are considered  sat-śāstra , or scriptures which lead one to the path of God realization.  Asat-śāstras  are just the opposite.
