OM contains all Vedas

* OM contains all Vedas *

त्रयीं तिस्रो वृत्तीस्त्रिभुवनमथो त्रीनपि सुरान्‌
अकाराद्यैर्वर्णैस्त्रिभिरभिदधत्‌ तीर्णविकृति।
तुरीयं ते धाम ध्वनिभिरवरुन्धानमणुभिः
समस्तं व्यस्तं त्वां शरणद गृणात्योमिति पदम्‌॥ २७॥

O, grantor of refuge and protection! The word `OM' consists of the three letters `a', `u' and `m'. It refers to the three Vedas(Rik, Yajuh and Sama), the three states (Jaagrat.h, Swapna, and sushhupti-awakened, dreaming and sleeping),the three worlds(Bhuh, bhuvaH and suvaH) and the three gods (Brahma, Vishhnu amd Mahesha).It refers to you yourself both through the individual letters as well as collectively; in the latter form (i.e . the total word `OM') it refers to your omnipresent absolute nature, as the fourth state of existence i.e `turIyam' (sleep-like yet awakened and alert state, as a fully- drawn bow).
