It has been made very clear for the readers that for learning the metaphysical sciences it is of utmost importance that one should liberate oneself from dispersed and scattered thoughts. When the thoughts are concentratively focused on one single point the concentrative abilities of the mind are developed. Those who have not completed the first lesson are advised to switch on to the second lesson only when they have completed the first lesson.
Likewise, please do not start this third exercise if the second lesson is not completed. One more thing is also required to be understood very clearly. As the fingers of the human hand, no two men could be equal in terms of their abilities to learn and achieve. Some are more capable than others. Those who are not ordained with more abilities should not feel inferior to others or discouraged, rather they should rejoice at the success of people with more abilities.
Having an inferiority complex amounts to rusting ones’ abilities. Those who have not succeeded fully should be striving more enthusiastically instead of losing heart. Success is bound to be yours.
The third lesson for mental concentration is as follows:
Close your right nostril with the thumb of your right hand after sitting in a relaxed posture. Inhale through your left nostril for seven seconds.
Hold your breath for 15 seconds after closing the left nostril with the small finger of the right hand. After 15 seconds remove the thumb from the right nostril and exhale through it for seven seconds.
Now inhale through the same nostril for 7 seconds and hold your breath for 15 seconds by closing it with the thumb. Exhale through the left nostril for 7 seconds after removing the small finger. This makes it one cycle. Complete 15 such cycles. This exercise is also done once in the morning and once in the evening before going to bed. This exercise would yield the best results if it is done on an empty stomach in an open and airy place.
All those students who are practicing these exercises are advised to have their dinner early in the evening. There must be a gap of at least three hours between the dinner and the exercise i.e. the exercise should be done three hours after taking the meal.
After this exercise of breathing either sit with legs crossed or in any other comfortable posture which suits you the best. Let the muscles of your body relax.
There (After succeeding in having this imagination with closed eyes. Start attempting to have it with) must not be any tension in any part of your body. Now close your eyes and imagine that there is a pool of mercury and you are submerged in that pool of mercury. Depth of this imagination is indicated with a tactual feeling of mercury. When this imagination further deepens the mind starts feeling the weight of mercury.
Silvery scintillations of waves start taking place in the mind. open eyes. Finally, when you manage to observe that the whole world besides you is submerging in the pool of mercury, your 3rd exercise is completed.
Muraqbah is not to be performed when you are lying or reclining against some support because it would cause you to sleep and the state which is required to be experienced in wakefulness slips into sleep. It creates this problem that the mind starts dreaming instead of observing in wakefulness and it becomes difficult to relate the things witnessed in dreams with one another.
