Once your intellect transcends the mire of delusion, you will attain indifference to both what has been heard and what is yet to be heard regarding worldly and heavenly pleasures.
Previously, Shree Krishna mentioned that those attached to worldly pleasures are drawn to the flowery promises of the Vedas, which advocate elaborate rituals for material gain and heavenly rewards. However, those illumined with spiritual wisdom no longer seek such pleasures, recognizing their transient and often sorrowful nature. Consequently, they lose interest in Vedic rituals. The Muṇḍakopaniṣhad affirms this sentiment, stating that enlightened sages transcend Vedic rituals, having discerned the temporary and sorrow-laden nature of pleasures derived from fruitive actions in this life and the celestial realms.
