Merging of Soham with Hamso.
Start rhythmic breathing. Breathe in and out with full awareness. As you breathe in, be aware of the breath passing down from the navel. As you breathe out, be aware of the breath passing up from the navel. Be aware of soundless, peaceful and relaxed breathing.
Now integrate Soham mantra with the breath. In this stage the form of consciousness is a continuity, So merging with Ham and Ham merging with So making an endless circle of Sohamsohamsohamso… Prolong the vibrations of So and join them with those of Ham. There is no pause in the breath; inhalation and exhalation follow inhalation. Thus, alternately introspect on Soham or Hamso without any break.
Now stop this practice and empty your mind. Experience emptiness. Focus your consciousness at the centre of meditation. Remove all thoughts. Again, after some time start the endless circle of Sohamsohamsohamso… At the end of the practice heighten your awareness of peace and rest. Mentally feel anandam (bliss), paramam (delight), sukham (happiness), shantam (serene) and mangalam (all auspicious lord).
