What is the use of the knowledge gained by us through discussions on the scriptures?

If scholars spend all their time in discussions without any practical sacrifice, there is no use. The intelligence and logic cannot touch the Lord as said in the Gita and the Veda (Yo Budheh Paratah, Namedhaya, and Naishatarkena). You do not discuss about your children constantly by such logic. Then why do you spend so much time on discussions about the Lord? Shankara said that excess of logic should be avoided (Dustarkah Suviramyatam). But the discussions and logic can be used to attain the knowledge of the Lord and the path following the Vedas as told by Shankara (Sruthimatah Tarkonu Sandheeyatam). Similarly, Sage Vyasa warns us about constant [excessive] logic in his Brahma Sutra “Tarkaaprathisthanat”. Therefore one should concentrate all the energy dissipated through words; mind and intelligence in the action like Hanuman.
