"In one of these yogis, the infused energy was aggressive and appeared like a stick of fire. In the other, it appears like a blue-white light which emanated a glow of white light."

Michael Beloved 

What do these statements mean, in what context:

1. "Infused energy was aggressive"
2. "blue-white light which emanated a glow of white light"

 Does it denote the person's subtle body personality (aggressive), or the energy emits a color when it gets absorbed on these subtle bodies?

Does the color of the Infused energy like fire yellow, blue-white light represents the grade of the infused energy?
