You follow someone only after establishing a trust that was done only after careful evaluation. Also, following blindly is not adovacted by Vedic Scriptures at all. But, at the same time, you should also have trust to some extent. Its a delicate balance that one has to maintain by way of using ones own intuition. Hinduism never advocates to follow blindly, especially when it comes to knowing or realizing of ALL PERVADING DIVINITY OR GOD OR ALLAH OR PARAMATMA OR HEAVENLY FATHER. It affirms one to have personal experiences that will make one affirm the existence of ONE AND THE ONLY ONE TRUTH AND THAT TRUTH IS THAT GOD IS ONE, GOS IS GREAT AND Most Importantly, GOD IS EVERYWHERE.
