Yes, ego does play a role in all aspects of life including Spiritualism. What is ego? In my understanding, the ego stands for 'an attachment to the false image of one's self'. When you perceive yourself as a body with a thought that I am so and so, the ego plays a role in whatever you do. Once you change the belief and perceiveyourself as a Soul or Spirit or Consciousness or a Spark or Energy or whatever you believe in, you go beyond body and mind. Once you are firm in this belief the ego would gradually subside.
Another approach is thinking one's self as an instrument of God. Before you do any thing you pray 'God you think, speak and act thorough me so that whatever I do is on the path of Truth'.
