'Understanding (vigñâna) is better than reflection. Through understanding we understand the Rig-veda, the Yagur-veda, the Sâma-veda, and as the fourth the Âtharvana, as the fifth the tihâsapurâna, the Veda of the Vedas, the Pitrya, the Râsi, the Daiva, the Nidhi, the Vâkovâkya, the Ekâyana, the Deva-vidyâ, the Brahma-vidyâ, the Bhûta-vidyâ, the Kshatra-vidyâ, the Nakshatra-vidyâ, the Sarpa and Devagana-vidyâ, heaven, earth, air, ether, water, fire, gods, men, cattle, birds, herbs, trees, all beasts down to worms, midges, and ants; what is right and what is wrong; what is true and what is false; what is good and what is bad; what is pleasing and what is not pleasing; food and savour, this world and that, all this we understand through understanding. Meditate on understanding.

In plain words: Understanding is greater than reflection. Through understanding we grasp the sacred books, the whole natural world, right and wrong, true and false, and this world and the next.
