Your cells are regenerating and dying constantly, you are not the same you were yesterday. Your cells and gene expression are different now than they were yesterday- the environmental, nutritional, and social conditioning around you left a mark on your genetic expression.

Address. Accept. Slow belly breaths. Let negative emotions and thoughts die. Connect with your deep inner self. Sleep. Renew. New light. Open your eyes- rebirth.

Meditation’s main focus is to connect you with your inner self. “The deep inner Self is the source of all knowledge, intelligence, creativity, and all natural laws that govern existence.
According to Vedic science, the deep inner Self activates the inner faculty (working consciousness), which in turn activates the physical body. A feedback loop is provided by meditation, in which a conscious connection is made with the deep inner self. The feedback loop to the deep inner Self provides inner peace and bliss, which removes the accumulated stresses of life and improves overall health. Meditation also improves telomerase activity, which helps lengthen telomeres-The protective cap on the end of chromosomes. Telomere lengthening is associated with prolonging life.

During meditation: “The properties of the deep inner Self begin to extend into the inner faculty, and since the deep inner Self is the source of all knowledge (which correlates with DNA on the physical level), the benefits of this process extend to all aspects of life – physical, mental, emotional, spiritual, etc.”
