When you breathe, think, or feel inspired, you are experiencing an aspect of the God. The Gods and Goddesses certainly do manifest through natural phenomena, such as lightning and thunder, plants, animals, and the elements and forces of nature. They work upon the human mind and heart too. When you experience mental exultation, an epiphany, or profound emotion there might be a Divinity behind it. It is wise to pay attention to nature and to your own inner reality, as these are used by the Gods to communicate with humanity.
Adrenaline pumps, there is a quick in drawn breath.
There is a feeling of awe, a tingle up the spine. The animal instinct or that sixth sense that alerts of us danger does not lie. Odin brings excitement and a feeling of enthusiasm, and anticipation of possible adventures, trials, wisdom or magic to come. Accompanying this excitement is a sort of mental clarity and focus, as if one has been lifted up to a higher vibrational level. I do not think the Gods do harm by this, nor do They violate free will.
