Kriya Yoga is a science of Self Realisation. It is non sectarian, not specific to one religion and not limited to personal capacity. The Hong sah (HS) technique is a master key to the concentration. The prerequisite capacity for meditation is concentration. Actually achieving concentration is difficult unless one can stop the senses tyrannical pursuit of their desire. For this purpose The Hong Sah technique is supreme. This sound 'Hong' 'Sah' is the sound of the breath as it enters and leaves the body via the nose. It is also the sound the personality energies after they have been synthesised to a singular form from their five fold nature. It is also the sound of the causal bodies life force investment in its personality instrument as it precipitates this life into its persona and as the life experience of its personality ascends to its soul. This dual sound also becomes round and reveals within itself the sound OM. The sound of the non-dual filament of the essence of the human soul and that greater consciousness it focalises.

The second and central meditation object, after one has achieved some success in concentration is the soul.   Patanjali recommends the sound OM. Conclusive epistemology is found through Ontology because if one knows the soul then one knows everything, because the soul is in everything and is the basis of everything. The syllable OM is actually the result of a triple sound: A U M. This tripe sound is the beginning, middle and end of the Sanskrit language. In fact it contains the all the other letters or sounds because they must be pronounced as the sound moves from A to U to M. Sanskrit is the oldest language and its structure is the foundation of ALL language on earth. Sanskrit means perfect and one example of this perfection is the energetic dynamic of OM (called Omkara).

What is of primary importance here is not Indian culture, Sanskrit or Hinduism, rather the science of vibration and its effect on consciousness resulting in dualistic states of awareness and non-dual states, which have been cultured in India, amongst other place. As the A is sounded and blends into the U the two become one -O- and in the oneness a third octave M  manifests. This is experienced as a triplicity which creates a singularity. As if  A thread is passed through the eye ' U ' of a needle into a world of M. This world of M, or OM is a peace which is beyond mental understanding because it is non-dual and the mind is a dualistic instrument, therefore the mind cannot understand it because it is non-dual. In the same way that an Indian can understand an Indian, the soul can understand the soul. For this reason stress will only be understood when one touches this sound. The instant the sound is touched it becomes real and in this realisation the ignorance accumulated through time is dissolved into non-dual eternal space where time is not. Thus the power of realisation. Thus the value of realisation.  

This sound dynamic is the central template of duality-non-duality in manifest-unmanifestation and its realisation - through kriya yoga meditation - is the the key component in making real that wisdom which causes freedom.

The system of Kriya Yoga meditation provides the simplest and yet most conclusive structure for hearing the sound OM. There are many schools and teachers of Kriya now, but for the average person with limited time Paramahansa Yogananda publicised two pertinent techniques. These techniques are not modifications but rather specifically selected from key Veda: HS and OM are to be found in Veda, Upanishads, Bhagavad-Gita, Yoga sutras, etc. Learn this
