Serenity is the steady state—emotions and experiences are ephemeral.
Perhaps one way to encourage meditation is to consider varieties of approaches to it.
The following may be rather unique because it is based on one of the best known passages from the Book of Genesis 2:7. The King James Version states “And the Lord God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul.”
The original Hebrew relates through various words the concept of breath and soul. But without delving too deeply into the varieties of soul according to Kabbalistic concepts, try to visualize God breathing the gift of the soul and therefore life into us through every breath.
Breathing in through our nostrils can be visualized as a passive act on our part, an active one by God who by doing so signifies ‘his’ desire to grant us continued life, literally from breath to breath. Allow our breath to slowly exit our mouths. Allow the process to continue as slowly or quickly as it flows. Allow the breath to pause at times as if God is considering the option of continuing to grant us life or not. It is ultimate submission to God, the Universe, Divinity, Ein Sof, Source etc.
Relax in the mystery of existence and stop trying to control what may not be in our power to do so.
