I understand that we can discriminate and make distinctions as to each ray, but to suggest that certain insights simply don't apply and have no value towards the overall understanding of one in particular I think is simply not true. You're aware that when energy moves from lower to higher it is the same energy, but it transforms and takes on new meaning. So aspects of courage will apply to red through violet. I personally like to approach the rays in a fluid manner, as I feel that attempting to distinguish them in all instances can be difficult since everything is related.
Ra very clearly states in 84.20 that blue ray involves "all communication", which I'm sure involves speaking to each other, and also that developing this honest clarity takes time. Sounds like aspects of courage to me, or learning to open up (clarity, honesty). Perhaps you don't like the word courage..inhibition? Embracing the self, uninhibited expression. These things also have a relationship to wisdom, and the balance between love and wisdom. Since that balance has to do with the self, how to best apply yourself without over-extension, embracing your needs etc., someone who is imbalanced towards love at the detriment towards themselves, is most probably holding their true feelings back. Gaining the courage to speak up most certainly involves blue ray and wisdom. How can you be a co-creator (the function of blue ray), giving feedback to others, if learning to speak your true feelings isn't a part of that ray?
