Thank you both for your replies.
I do get the impression that a person could perhaps receive or release such energy in the case of a sincere, non-repressed expression of love/affection, or maybe something similar. I'm not sure that the energy itself would be freely available in the long term as a result, though. Maybe the channels allowing such energy to flow would be clearer as the feeling center might be less clouded in such a case. I get the impression that a certain "amount" of energy is released by an inspirational experience, but I do notice that by remembering the inspirational moment, I can call up a new wave of energy. I wonder if analyzing exactly what essential idea or principle inspires us in each case might be useful in allowing us to "inspire ourselves to action" when it is required of us. For example, I tend to be inspired and invigorated when I see examples of "breaking the limit"; such as, when Neo "awakens" in The Matrix; or, when the horse, Secretariat, speeds far ahead of the other horses in a long distance race, which was considered to be "impossible". Maybe we need to identify the specific principle so that we can identify it in its larger context. For instance, in the examples I gave, I think what truly inspires me is the idea of breaking through illusory limitations imposed by others and self, and thus realizing true freedom. I think the main thing to defend against in these cases is rash action or reckless wasting of the energy provided; I find it can produce a feeling of being "powerful", which makes me wary of getting carried away. My visualizations can seem more "real" during this period, and I become physically restless. Also, it can keep me from wanting to sleep when I need to. However, these may be due to my particular conflicts. I have the feeling that it can be harnessed through self-awareness, and be used for motivating action. In fact, judging by my experiences the last couple of days, perhaps it can act as a fuel for self-work as well, at least if one catches it before the energy is expended.
Or so I think...
