Using Self Enquiry to aid your practice
Self enquiry is an ancient mind training practice that was made famous by an extraordinary Indian saint by the name of Bhagavan Sri Ramana Maharshi who died in the mid part of the 20th century. It is, he said, the most direct route to Self Realisation and was to be favoured above all else if the mind was capable and strong enough to use it.
Self Enquiry is vastly different from EFT or YouTapping in that it does not even propose looking 
at the issue or situation itself but rather supposes that you should take hold of the first thought - the 'I' thought whenever it arises and bring it back to its source - the Self. However, you may also feel the need to tap as you are doing self enquiry. Though it is not something that is absolutely necessary, it may aid you to a degree to do so.
Self enquiry is the next logical step after EFT and YouTapping as it will greatly assist you to gain greater peace in your life, but generally it is not something someone can use until they have at least a modicum of mental peace. Therefore EFT and YouTapping are ideal precursors.
Behind the conscious and the subconscious minds, lies the true Self or 'The peace which passeth all understanding'. It is the silent watcher of your life and the closest you will normally get to experience it is in deep sleep when the mind is dormant.
The following information is a taster of the practice of Self Enquiry. More information can be obtained at the following website : http://www.sriramanamaharshi.org/
In the famous book entitled 'Who Am I?' ('Nan Yar'), Sri Ramana was asked
'What is the nature of the mind?'. His answer is as follows:
What is called ‘mind’ is a wondrous power residing in the Self. It causes all thoughts to arise. Apart from thoughts, there is no such thing as mind. Therefore, thought is the nature of mind. Apart from thoughts, there is no independent entity called the world. In deep sleep there are no thoughts, and there is no world. In the states of waking and dream, there are thoughts, and there is a world also. Just as the spider emits the thread (of the web) out of itself and again withdraws it into itself, likewise the mind projects the world out of itself and again resolves it into itself. When the mind comes out of the Self, the world appears. Therefore, when the world appears (to be real), the Self does not appear; and when the Self appears (shines) the world does not appear. When one persistently inquires into the nature of the mind, the mind will end leaving the Self (as the residue). What is referred to as the Self is the Atman. The mind always exists only in dependence on something gross; it cannot stay alone. It is the mind that is called the subtle body or the soul (jiva).
The following questions were then put to Sri Ramana:
What is the path of inquiry for understanding the nature of the mind?
That which rises as ‘I’ in this body is the mind. If one inquires as to where in the body the thought‘I’ rises first, one would discover that it rises in the heart. That is the place of the mind’s origin. Even if one thinks constantly ‘I’ ‘I’, one will be led to that place. Of all the thoughts that arise in the mind, the ‘I’ thought is the first. It is only after the rise of this that the other thoughts arise. It is after the appearance of the first personal pronoun that the second and third personal pronouns appear; without the first personal pronoun there will not be the second and third.
How will the mind become quiescent?
By the inquiry ‘Who am I?’. The thought ‘who am I?’ will destroy all other thoughts, and like the stick used for stirring the burning pyre, it will itself in the end get destroyed. Then, there will arise Self-realization.
What is the means for constantly holding on to the thought ‘Who am I?’
When other thoughts arise, one should not pursue them, but should inquire: ‘To whom do they arise?’ It does not matter how many thoughts arise. As each thought arises, one should inquire with diligence, “To whom has this thought arisen?”. The answer that would emerge would be “To me”. Thereupon if one inquires “Who am I?”, the mind will go back to its source; and the thought that arose will become quiescent. With repeated practice in this manner, the mind will develop the skill to stay in its source. When the mind that is subtle goes out through the brain and the sense organs, the gross names and forms appear; when it stays in the heart the names and form disappear. Not letting the mind go out but retaining it in the heart is what is called 'Inwardness'. Letting the mind go out of the heart is called 'externalisation'. Thus when the mind stays in the heart, the 'I' which is the source of all things will go, and the Self which ever exists will shine. Whatever one does, one should do without the egoity “I”. If one acts in that way, all will appear as of the nature of Siva (God).
