भारोऽविवेकिनः शास्त्रं भारो ज्ञानं च रागिणः ।
अशान्तस्य मनो भारः भारोऽनात्मविदो वपुः ॥
- योगवासिष्ठ, वैराग्य
An idiot would find the scriptures heavy. A person who enjoys worldly pleasures finds knowledge heavy and unbearable. A restless man finds his mind heavy. If one does not know his self, he will find his body heavy.
