Of course, everything is an illusion, because it’s all based on how we perceive things. Therein lies the choices, such as they are. For instance, we perceive electromagnetic wavelengths differently from other species, because of how we are built. The same goes for our perception, or interpretation of our perception, of self and ego. We can’t eliminate these, anymore than we can eliminate our liver, but we can choose how we perceive these. Meditation, mindfulness, and even psychedelics can expand our understanding of these essential elements of our being.
