Meditations: Heat sensation during Meditation on Sigil

Yesterday I was praying to Father Zeus. After prayer I was meditating on His Sigil. I felt very hot energy, but only on my hands.
Today after Standard Ritual I was also meditating on Father Zeus Sigil. I had heat sensation in my whole body only for a few minutes.
Is it possible that this feeling have any meaning? Or it’s just bioelectricity ?
