@ my man...... GURU = GU + RU. GU means darkness and RU means that which removes darkness. So, your guru can be anything. It doesn't necessarily have to be a human being. I have so many gurus like Sun, Trees, Fire, Forest, Space, Hunger, etc.. Also, guru can appear in your dream as well. When ego slowly fades away from you mind, celestial divine being and Siddha Mahapurush from Deva Loka can come in your dream and guide you.
The main important thing is that you always apply 'self-effort' from your side. When you are ready, guru automatically appears in your life and can appear in any form. So, don't hanker after gurus if you don't have one. All the necessary ingredients and environment will be provided to you when you are gradually self-transforming.
