We so often identify ourselves with our thoughts as if it were the absolute truth. I know personally, the mind stands in its own way, challenging me to see the purity within itself often times. It is a practice to allow the observation of the mind to take place.
Yogiraj Achala tells a story that so brilliantly simplifies analogously, the truth of thought. "Yogiraj takes his youngest son to the Mississippi River. The son, looking into the river, asked his dad if the river was polluted. Yogirij resonded that no, the river is only carrying the pollution, the river iteself is pure. Our minds are like the river carrying things in it. If we identify with what the mind is carrying-thoughts, stories, beliefs-then we will think we are those things. However, if we identify with the Divine within us (the pure river) and merely watch the thoughts float by, we will know we are simply carrying the thoughts, stories, and beliefs; they are not who we are."
Kelly McGonigal is a profound leader in the field of science, weaving mindfulness and compassion into her work. Always inspired with great admiration for what she embodies. I offer this video as a way to shift your perspective on stress. Perhaps just learning a few new things about how our brain and body connect. -Peace and light
