The term Pseudo Vedantist has been explained by Swami Sivananda in an article called "Pseudo-Vedantic Student".
Vedanta in the hands of raw and unregenerate persons who lack purity and devotion and who have not removed the impurity of their hearts through untiring selfless service with Atma-Bhava and Kirtan and prayer, is perilous. It is like a sharp razor in the hands of a child. Instead of expanding their hearts the Vedantic study will thicken and fatten their egoism. They fall into the deep abyss of ignorance. There is no hope, for them, of being lifted up, as their heart is filled with foolish, Tamasic, obstinacy, false Vedantic pride and self-superiority and false Tushti (satisfaction).
Does any scripture mention or explain the term Pseudo Vedantism, which many of the peetadhipathis appear to be following?
