Googling on relationship between rhythm and memory – you will find some nice research articles.
The rhthymic meter that is known as the chandas did its bit to trasmit the hymns that are also referred to as the chandas by memory via the oral tradition for millennia. Even as taitrIya Upanishad venerates the Omkara as the amRta that sprung up from the chandas ( meaning the verse or hymn) – we can do a reflexion on it by using the later meaning of the word chandas, by deducing that the chandas the rhythmic meter, to begin with, provided amRtatva to the chandas the hymn (manifest) before the Omkara (unmanifest) can spring forth amRtAt.
So to provide an interesting story line, the moon bestows amRtatva on all the herbs – which in turn bestowed amRtatva on the rishis even to the end sometimes. During praLaya ( the great floods) the sAma vEda rishis apparently perished in great numbers. The yajur vEda rishis held on to or floated on the dharbha or kusa grass ( as you might have read darbha for ritual purpose is harvested after the full moon day) which got it’s amRtatva from the moon ( ask the cult that practices lunar phase planting). They utilized the chandas the meter to pass down the chandas the hymn immortalizing it – so we could all have a shot at the immortal experience of Omkara as it springs forth.
Again I am not sure about the preponderence of darbha in Yajur vs. sAma. Somebody knowledgeable can throw light on it. If that is not accurate just relish the story nevertheless!
To conclude it with a twist: When Anantakrishna Iyer (
