Even though we have hot and cold days, we always have crisp clear, calm, and cool morning air, beyond heat and chill.
Even though we have the new, crescent, half moon, etc., we always have the full moon, beyond different phases.
Even though we have ups and downs, births and deaths, we always have unconditioned peace, beyond vicissitude.
Even though we have many expressions – original face, unborn mind, etc. – we always have awakening in unconditioned peace (正法眼蔵涅槃妙心), beyond transmigration.
