Acharya Prashant explains that the Vedic mantras and Upanishads represent a scholarly and sophisticated way of expressing the truth, whereas saints use the language of the common people. He suggests that one should choose a path based on their own mental disposition; if the scholarly language feels difficult, one can turn to the teachings of saints and return to the Upanishads later. He emphasizes that the Upanishads are not intentionally complex, but their elite style reflects the refined atmosphere of the time they were composed. He advises against approaching these scriptures with an ego that demands immediate and total intellectual comprehension.
