Why did Adi Shankaracharya targeted Jain temples and converted them with Shiva Lingams? Why did Adi Shankaracharya targeted Jain temples and converted them with Shiva Lingams? “ chittasya SuddhayE karma “ - AdiSankaracharya. Means any action should result in purification of one's mind. That action is real action and one should do only such actions. Vivekanand said “ I tell only the greatness of my religion. I will not criticize other religions. Because my religion is the mother of all other religions “. Vivekanand followed the philosophy of AdiSankaracharya. Is it believable that AdiSankaracharya targeted Jainism and Jain temples?. Where is the time for him to do such acts?. For a building or religion, the foundation must be strong. Then only it will remain for longer time. It's not difficult for anyone to find reason for the downfall of those religions. AdiSankaracharya is a visionary. He correctly imagined how we would be in 21st century. We have no time even to chant a nama 108 times, read a sloka or hear some discourse. We are busy with our livelihood. Unless we work hard for 10–12 hours per day, we cannot have a comfortable life. Under these conditions, whether it is possible to do rituals like fire Homams daily for long hours?. This what AdiSankaracharya thought. Vedas proposed mainly two paths for Moksha - karma kanda and Jnana kanda. Karma kanda is about fire rituals etc which are time-consuming and expensive. Jnana kanda is reading and listening to Puranas, chanting some namas or Slokas etc. AdiSankaracharya thought, in later years, people will be busy with livelihood and may not find time for rituals. So he preferred Jnana kanda and spread it through out the country. In AdiSankaracharya time, karma kanda was in full swing and vedic scholars like kumarilabhaT, Mandana Misra and others who believed only in Karma kanda spread the rituals. AdiSankaracharya travelled through out the country for 3 times by walk, argued with all eminent scholars that Jnana kanda will be better for future generations, convinced them and defeated them. To spread this Jnana kanda, he gave several texts and Slokas by way of Soundaryalahari, Sivanandalahati, narayana stotram, pancharatnas, ashtakas and so on. He wrote detailed explanation for Vishnu Sahasranamam and Brahma sutras. Because of his hard work, we are all spending peaceful and comfortable life just by chanting some namas daily without worrying much about fire rituals etc. Let us be grateful to that Great Visionary who reestablished Sanatanadharma. Because of him only, though country was under slavery for 1000 years, nothing happened to Sanatanadharma. Subhamastu
