It is cer­tainly typi­cal of knowl­edge, that one can profit from it. This profit may be of vari­ous na­ture:

1. Mu­si­cal knowl­edge can impart prac­ti­cal wis­dom of life to the un­der­stand­ing and thus give our con­fi­dent ac­tion sure suc­cess.

2. Mu­si­cal knowl­edge can en­cour­age the feel­ing, can in­crease the alert­ness on the level of feel­ing and thus refine the proc­ess of feel­ing.

Thereby our emo­tional life be­comes more and more aware of the en­er­gies in­her­ent in it.
This in­crease of en­ergy in the field of our feel­ing we ex­peri­ence as hap­pi­ness.

So far, this in­crease of hap­pi­ness is not con­sid­ered part of the field of cog­ni­tion, but still it is the re­sult of a cog­ni­tive proc­ess on the level of our feel­ing. Nev­er­the­less, most of us strive for hap­pi­ness, and not with­out good rea­son are the wise con­sid­ered happy.

3. Mu­si­cal knowl­edge can bring sta­bil­ity to man in his en­tire thought and ac­tion from the depth of his feel­ing and un­der­stand­ing, be­cause feel­ing and un­der­stand­ing to­gether go through the mu­si­cal proc­ess of know­ing and are both placed into the state of su­preme cog­ni­tive po­ten­tial.
