    I get anxious at night.
    My heart palpitates when i think of what’s going on in this small world. That’s why i rely on meditative prayer like the Rosary and all of its Holy Mysteries.
    Thank you for the brief.
    And i am not a bot.

    Powerful. A heart at rest & in alignment feels eternal – a sensation within the body”of all the time in the world.” The inverse makes us perceive time as a limited or rushed endeavor. Time is relative. May we experience more deep & rejuvenating rest + recovery, & more activities that are harmonious experiences & helpful for our mind•body•soul to thrive in this lifetime.

    The heart is a sophisticated mechanical pump. Our fears, feelings, memory, intelligence, and emotions (including love and hate) are in the mind, whose physical base is the brain. 💕☮🌎🌌

      Actually, those things are distributed throughout the body. Your cells, muscles, and other organs have their own memory and are smarter than you think. Abilities acquired in music and martial arts, for instance, are not located strictly in the brain– the reaction times involved are faster than nerves can transmit signals between the perceptual organs, brain, and muscles, round-trip. Processing is specialized in certain areas, but your whole body remembers things, not just your brain. Cells are smarter than you think.

    I wonder if this is what happens when people experience “bullet-time”. The heart slowing or maybe even skipping a few beats. This also seems to correspong with exhalation. Something I’ve noted during chant in Church. I do the eson, which is basically a continuous note of very long duration. At first it is difficult to maintain without breathing in but at some point you get in the zone and it’s like you just have breath for days. I suspect partly due to unusual gaseous saturation of the blood, from the continuous pressure pushing oxygen and other gases through the lungs, but there is definitely an exotic temporal quality to this as well, which makes the experience seem both timeless and… eternal. It feels like many hours on the one hand, and on the other like no time at all. But certainly I have experienced similar occasions in normal life where time seemed in slow motion. I think during such times, as my brain revved up to double or triple my ordinary frame-rate, I never breath in– it’s like one very slow, almost imperceptible exhale. Something I’ve noted during which my heart-rate massively slows and smooths out. In contrast, my heartbeat during inhalation is strong enough to see my clothing shake in the mirror. I think I first noticed this years ago during dive-training for open-water scuba, where you have to pass certain tests for breath-control.
