0 Seeker! Every moment remain engrossed in the practice of Surat- Shabd-Yoga [union of the attention-faculty of the soul with Divine Light and Sound within during meditation] for there is no other comrade like the Word. Close your outer ears and then listen to the reverberations of the Word inside. The Word will drive "I-ness" (arrogance, self-centeredness, ego) out of you. Gain access to the Word and then you'll attain to steadiness and control of mind. After that you'll perceive the glowing and brilliant light of the flame and remain rapturous in the resonance of the Word every moment. You will then feel sick, disgusted and satiated with the objects of pleasures and forsake all of them for you would have soared high and heard the sonorous and resonant sound of the Word that is rich, deep and impressively loud.
The guru directs that you must remain contented and engrossed in that Sound; and then you will hear the diapason and crescendo of the sound (glorious and harmonious burst of musical sound and gradual increase in its volume). Then the surat [soul] rises from there rapidly, as if walking with heavy or noisy footsteps, impressively, and arrives at Sunn (Spirit-Sphere) hearing the euphonious tinkling sound. Thereafter, you will hear the sound produced by overtones rather than volume and pitch -- that of timbrel and tambourine; what shall I say about the majesty of the Sound which is infinite and unlimited. Whatever I may talk about it, it will be found wanting. This is a matter which is enigmatic and mysterious; how can I unravel its mystery. The surat [soul] now gains access to the depths and dimensions of the Spaceless and Timeless (Adhar). It now sits with her beloved Lord enjoying his perennial blissful company. All the darkness and dirt of the inner recess of the heart is now eradicated; showers of Sound are falling like murmuring rain. Inside you, as the light spreads, drops of ambrosia fall as the drops of dew. The mind has become fed up (annoyed and bored) with all other modes and methods (except Surat-Shabd-Yoga); the surat is now constantly applying to its wounds the healing and soothing balm of the Word (Sound). I now surrender my body and mind and all to the guru; Radhasoami [Lord of the Soul] speaks in this wise, time and again, with every breath. -- Swami Ji Maharaj Sar Bachan Radhasoami Poetry, Volume One "The Quintessential Discourse Radhasoami" Translated by M.G.
