Om for going inside and Soham to remain awake until Sohang Dhun Emerges

Yes, this is true according to esoteric Sant Mat and Kabir Panth lineages. In these esoteric meditation practices, Om (ॐ) and Sohang (सोहं / Soham) represent internal spiritual sound currents and specific stages of consciousness:Om (The Inward Journey): The sound syllable Om is viewed as the creative primordial seed sound associated with the universal mind or Brahm. In internal practice, it represents withdrawing your attention from the external sense organs and going deep inside the inner spiritual sky (Ghat Bhitar).Sohang (Remaining Awake/Aware): Sohang literally translates to "I am That" (identifying the soul with the Supreme Being). Kabir frequently warns seekers against spiritual slumber (Agyan or ignorance). Reciting or synchronizing Sohang with the natural flow of the breath serves to anchor your consciousness so that you remain fully awake, conscious, and aware without falling into dark physical sleep or mental delusion.Together, they form a methodology of internal devotion: Om draws your scattered awareness inward, while Sohang ensures that once you are inside, you remain completely awake to the Divine Light and Sound.

Dadu Dayal about Kabir

साधो ऐसा देस हमारा

महरम होए सो जाने साधो ऐसा देस हमारा।

1. वेद कतेब पार नहीं पावत कहन सुनन ते न्यारा।

जात वर्ण कुल किरया नाहीं संध्या नेम अचारा।

2. बिन जल बूंद परत जिंहि भारी नहीं मीठा नहीं खारा।

सुन्न महल में नौबत बाजे किंगरी बीन सितारा।

3. बिन बादल जहाँ बिजरी चमकै बिन सूरज उजियारा।

बिना सीप जहाँ मोती उपजै बिन सुर षब्द उचारा।

4. जोत ले जाए ब्रह्म जहां दरसे आगे अगम अपारा।

कहे कबीर वो रहन हमारी बूझे गुरमुख प्यारा।
