What is the use of this Sutra , or why one should even try to understand this Sutra is a pertinent question here . Its importance is mainly in Knowledge meditation wherein we come to ''Know'' where we are located at a particular time in thought . An attempt is made to explain how it works .
Apart from the body , we are a mixed consciousness (or undifferentiated) of the mind, intellect , Memory and Ego (the empirical ). All these together as one are known as 'Chitta' or 'Chittam' in the Veda. Modern day interpreters have given it the name ''Mind stuff''. ''Inner Equipment'' and other names such as Manas, Buddhi, Orma (memory) and Ahamkara (Empirical ego) . It is not possible for even very good practitioners to exactly point out and say ''this is the mind'' it ensconces so much area , or this is the intellect and its ambit is so much and so too with the other two principles - they are like salt in sea water and cannot be differentiated in an exact manner . But by astute observation it is possible to differentiate them in an inverse manner . ie. by the properties and laws of each of the constituents comprising the Chitta we can say when we are in a particular modification of the consciousness. Kramam helps ascertaining the differentiartion of this consciousness so that we know when we are operating on memory , or from mind, or from senses , or from the ego or from the intellect . Another thing to be understood is that all these are held in knowledge (Pure Consciousness which is both the binding force or ''Will'' ). And consciousness pervades through and through and is contiguous , by which
one means that it is unbroken and so no delineations are there in consciousness (Knowledge ) . So it is nigh impossible to ''seggregate'' the mind etc and indicate it as one would an external or internal object - since it is intrinsic to the person concerned or attempting a foray into the self. Another factor is that people ''imagine'' consciousness to be some kind of feeling , or one of heaviness (as if one woke up from deep sleep with a head full of sleep etc ). No this is not so for this is only an undifferentiated feeling which includes the consciousness of the body . (A type of phantom consciousness) . Consciousness is knowledge and knowledge is subtle and pervades all the above principles including phantom consciousness etc which are always cognized by knowledge . THis is the backdrop of awareness one should have for the understanding of the sutra Krama(th).
If we observe closely - we can find that when a person says or remarks "He spoke rudely to me, and I did not quite like what he said , so I asked him to be civil - he continued and so I hit him ''.
Here what has happened is that - the person who has remarked this has located himself firstly in the Body and quickly migrated to the ego via the intellect - He ( Sight or Duality as expressed as another person ) spoke (cognition of sound through the sense of hearing ) Rudely (Feeling and Knowing as signified by the Intellect) to me (Empirical ego tht is yet undifferentiated) etc etc in the reverse manner from Ego (I) Feeling (Intellect& Knowledge) Addressing the other person (as apart - sight ) lastly Physical (hit ).
Essentially the person in the example has very quickly in a series (though it may appear as if instantly ) succeedingly located his consciousness of himself (knowledge) in various points which comprise the sense organs (being 5 also known as the organs of knowledge ) and Intellect and other paraphernalia . Now a question may occur where is the mind ? . The mind is the place wherein the person ''Be'' held the image throughout this sordid affair , so that he experienced it as real , any breaks being supported by his own memory . This is only a gross example , one cannot go into too much about all these things practice is required . similarly in meditation with thought we can place the thought arise from memory (which is the inner world ) and then the thought becomes (sight, sound, smell, taste )
and in cases touch meld to become feelings and intellect brings out the exact replica of what was seen and enjoyed in every detail . This type of perfect memory can be had , by using krama (where the time interval is so small so as to be almost non existent ) to know (in the inner world ) when one is in a particular modification , over time patterns can be recognized for the mind, memory, ego, different senses and intellect (lesser knowledge or manifest knowledge) . An then intuition takes over or Gnosis which becomes uninterrupted knowledge of the manifest . It is about half way mark towards total undistanced knowledge . It is the Meditation on U in the meditation of Omkara.
Hope I have been helpful , my abilities to express myself more accurately in English only extend this far .
