Machshava:

Ethics,  Middot,  Mussar,  Rav Kook 

Description

Usually heavy topics with important ramifications are relatively difficult, & that's why it's surprisingly easy to speak, even though words can extremely help or harm (gossip, embarrassment). Rav Kook suggests that God made it relatively easy to speak so that the important benefit can be reaped without much effort, with many halachic ramifications, as well, e.g. oaths, vows, kidushin, hekdesh & making people feel good with compliments, encouragement, etc. Even a small scream without words, usually activates us to action. Rav Kook also writes about the order of proper speech, that begins with thought, which leads to words, which lead to actions, & the special power of words in Eretz Yisrael, L& of Hebrew (Lashon HaKodesh) & Prophecy.
