Owing to its supremacy, Omkar is the bridge, the link between the other forms of yoga, precisely mantra yoga, bhakti yoga, hatha yoga and raja yoga. Daily practice of Yoga should include at least 10 chants of Om.
The Om chants should be rhythmic and slow. While chanting Om, irrational pause, frequent change in the pitch, too loud volume, inhalation through the mouth, etc., should be avoided consciously.

One should take into consideration one's capacity of breath, and then chant Om appropriately. Forceful chanting with the attitude of competitive spirit, stubbornness and with unnecessary contraction of the stomach is strictly prohibited. If chanted properly the effect of Omkar would be pleasant and peaceful and will not cause, fatigue, laziness or any sort of breathing problem.
