For me, this energy in nature that you are describing and responding to is Shakti, the primal feminine creative force of the Universe. It’s sex energy, but not only in the strictly sexual sense but also in the broader generative, creative sense as well. I’ve been wanting to write something more about this, and maybe I will at some point but you did a great job with it! Below is what I wrote on this last year.
“After all, sexual energy isn’t only about coitus. In fact, it doesn’t even necessarily have to be about sex at all. Sexual energy is simply life force energy. It’s the generative juice of the Universe and that juice isn’t only for making babies; it’s about creating love and intimacy, but also art, music, literature and in truth, new endeavors of any kind. It’s a sustaining force, but also a healing and a nurturing one and we revel in it whenever we can.”
