The other meditation is basically you seeing the energy of reality. We’re all energy, the basis of reality is energy and our reality is created from energy projections that oscillate by the frequency of our thoughts created into manifested form. When we meditate we invoke inner stillness, when we’re in a place of inner stillness we open ourselves up more in the present, NOW moment. when we are more present, we’re more in tune with Earth and her energies this is why when you are present you are more in tune with seeing/feeling energy. It shows you are more grounded. When we are not in a place of present mind, it’s harder to tap into these currents because we are not fully connected to our body. IF we’re too worried about money, a test, anxiety, someone waiting to text us back, how long we’re meditating even, we can’t fully be present with ourselves. This is what ego is about, it’s all the mind chatter, when we’re able to let go of the resistance of our Ego thoughts and feelings, an entire new universe opens up that grounds us in the NOW. This is when we can see energy, light, swirls of energy orbs across the sky, read into auras, etc. This is because we’re staying more present-minded with our energy body. The more we stay in this circuit the more we get stronger with our energy bodies and stronger within our inner mind. So what you saw is merely the beginning of meditation, meditation is truly a different way of life itself. It shows you have an entire universe inside of you just waiting to be explored.
Hope this helps you!
