Found it

Been reading the PDF version of Think & Grow Rich. I'm in chapter three. Amazing stuff, just the way he presents things makes them sink in. I can feel the positive emotions welling up as I read. A VERY good thing.

Anyway, near the beginning of chapter three, he mentions something that I kind of knew, but couldn't really put my finger on it. Here's a quote:
     "The emotions of FAITH, LOVE and SEX are the most powerful of all the major positive emotions. When the three are blended, they have the effect of "coloring" the vibration of thought in such a way that it instantly reaches the subconscious mind, where it is changed into it's spiritual equivalent, the only form that induces a response from Infinite Intelligence."

A couple pages later is:
     "... consider again the statement ALL THOUGHTS WHICH HAVE BEEN EMOTIONALIZED, (given feeling) AND MIXED WITH FAITH, begin immediately to translate themselves into their physical equivalent or counterpart.
     "The emotions, or the 'feeling' portion of thoughts, are the factors which give thoughts vitality, life and action. The emotions of Faith, Love and Sex, when mixed with any thought impulse, give it greater action than any of these emotions can do singly."

So, there you have it. Being alone you may be able to guess which two of these three I'm missing. Makes sense to me anyway :-).
