Understanding the designated sound representation and method of worship for Brahm (Kaal) is a central topic in Vedic scripture. In Yajurveda Adhyay 40, Mantra 15, the knowledge-giver of the Vedas (Brahm) explicitly reveals his primary single-syllable mantra—Om (ओ३म् / O3m)—and provides clear instructions on how it must be integrated into daily spiritual practice alongside every breath.
This Vedic instruction directly aligns with Bhagavad Gita Chapter 8, Verse 13, confirming that the speaker of the Vedas and the speaker of the Gita are the same entity (Brahm/Kaal) presenting the exact same spiritual mandate.
Sanskrit Verse: वायुः अनिलम् अमृतम् अथ इदम् भस्मान्तम् शरीरम् ॥ ओ३म् क्रतो स्मर क्लिबे स्मर कृतम् स्मर ॥ १५ ॥
Transliteration: Vayuh Anilam Amritam Atha Idam Bhasmantam-iti bhasma-antam Shariram, Om Krato-iti krato Smar Klibe Smar Kritam Smar || 15 ||
The instructions given in Yajurveda 40.15 mirror the command set forth in Bhagavad Gita Chapter 8, Verse 13:
Sanskrit (Gita 8.13): ओमित्येकाक्षरं ब्रह्म व्याहरन्मामनुस्मरन् । यः प्रयाति त्यजन्देहं स याति परमां गतिम् ॥ १३ ॥
Meaning: Chanting the single-syllable mantra Om (representing Brahm) and remembering Me continuously while leaving the physical body, a seeker attains the supreme state achievable within that domain (Brahm Lok).

YAJURVEDA ADHYAY 40, MANTRA 15 BHAGAVAD GITA CHAPTER 8, VERSE 13
• Identifies **Om (ओ३म्)** as the core mantra. • Confirms **Om (ॐ)** as the single-syllable mantra for Brahm.
• Demands remembrance until the body turns to ashes. • Demands remembrance at the time of leaving the body.
• Destination: Relative immortality (*Amritam*). • Destination: Highest state of Brahm's realm (*Brahm Lok*).
While Yajurveda 40.15 and Gita 8.13 establish Om as the authentic mantra for Brahm (Kaal), subsequent scriptural verses clarify its specific reach and limitation:
Yajurveda Adhyay 40, Mantra 15 establishes that the designated mantra for the worship of Brahm is Om (ओ३म्). The verse instructs seekers to perform this remembrance in harmony with their incoming and outgoing breath (Vayu) with deep yearning and dedication throughout their lifetime.
This Vedic command is identical to Bhagavad Gita Chapter 8, Verse 13, confirming the unity of message across both scriptures regarding the practice and realm of Brahm.
