“Om Namo Bhagavate Vasudevayah”
Dear devotees we all keep using these divine words, almost in all worship process, puja,havanas etc. Many of us would be very curious what these words really mean. I remember, some members have asked me to explain these words.

These words are the primary divine sound to represent the supreme himself. Bhagvan Shri Krishna himself explain this to Pandav Prince Arjuna: Shlika 23 through Shloka 28 of Chapter is to define all these three words. Here I would put the very first Shloka which defines the meaning of these words. In subsequent posts, I’d given descriptions of all other shlokas.
-------------------------------------------------------------------------
Ch17:Sh23
om tat sad iti nirdeso brahmanas tri-vidhah smrtah
brahmanas tena vedas ca yajnas ca vihitah pura

Om Tat Sat is three eternal types of Presentation( i.e. Description, Narration and Reference ) of Supreme Bramhan. In ancient times, they ordained the Bramhanas, the Vedic scriptures and the performance of yajna.
-----------------------------------------------------------------------
It is very clearly defined in this Shloka, these three syllables are the primary virbratory sound of the supreme Bramhan Shri Krishna itself.

These three words must be used at all the auspicious occasions like Yajna, Tapa, Austerities, Charity and any worship. The use is these words purify the whole auspicious process of Yajna or Austerities.

At other places, Lord of the worlds Shri Krishna has clearly defines, that Om is the very representation sound of him: please have these references:
--------------------------------------------------------------------------
Ch9:Sh17(Line1:part1)
vedyam pavitram omkara

I am knowable pure syllable “OM”.

Ch10:Sh25(Line1:part 2)
giram asmy ekam aksaram

Of narration(vibration) I am holy syllable “OM”
---------------------------------------------------------------------------
We all know all our actions and our activities are constantly under the effects of three Gunas which are the primary causes of binding these soul to this material world. Even Yajna and austerities involve those physical objects which are full of three gunas.

But using these divine vibrations of “Om Tat Sat” the process of our worship, Yajna or any such auspicious process is filled with the divine vibrations of Supreme Bramhan Shri Krishna.

Using these words in our auspicious is the guarantee of us following the divine order which would bring blessings of Lord to us.

In next posts I’d give details of each of the words separately. I hope this post will help you understand the meaning of these divine syllables.
