One of the oldest mantras is the world is The Gayatri mantra which states, "Everything in the heavens and in the earth and in between is arising from one effulgent source. If my thoughts, words and deeds reflected a complete understanding of this unity, I would be the peace I am seeking in this moment." It's just sometimes we forget. We forget our true nature. We forget our source. It's nice to know that forgetting who we are is also very natural. Don't beat yourself up about it because we all do it. The question is how do you set those practices up in your life to help yourself continuously remember?
