Simplicity and Profoundness
The first one is the very famous "asatoma sadgamaya" from the Brihadaranyaka Upanishad.
In english script:
tamaso ma jyotirgamaya
mrutyorma amrutam gamayah
Om! shantih shantih shantih ||
(take me) from ignorance to knowledge
from darkness to light
from death to immortality
peace, peace, peace
Simple, straight and to the point.
I still remember, when I was just beginning to make half meaningful sentences, how my grand father would stand with me with folded hands in front of the family pooja room, and help me recite this shloka. I can claim to remember this because, I have a recording of this with me reciting the shloka with my grandfather. My baby voice with that of the gruff smoke hardened voice of my grandfather.
The second one is the equally famous "purnamadah purnamidam" from the Ishvasya Upanishad
In english script:
purnasya purnamaadaya purnamevavshishyate |
Om! shantih shantih shantih
And a rough translation:
this is complete, that is complete from this complete comes that complete
if this complete is taken out of that complete, only completeness remains
peace, peace, peace
Many tomes have been written about this particular shloka for its profoundity. It might seem incoherent at first glance, but taken in its entire context, many people would aver that it encapsulates the entire advaita philosophy in it. There are many interpretations of this shloka. It is something that can really give a feast for thought. In spite of all that I said about this shloka, sometimes I wonder is this shloka all about simplicity itself?
Here are some good links that discuss this shloka
