gradually, as the mind becomes fixed, the potencies of the lower stages are overcome by the potencies of this stage, so that the mind flows in a calm current and at last the higher prajñā dawns, whereupon the potencies of this state also are burnt and extinguished, the citta returns back to its own primal cause, prakṛti, and purusha attains absolute freedom. The first four stages of the samprajñāta state are called _madhumatī_, _madhupratīka_, _viśoka_ and the _saṃskāraśesha_ and also _vitarkānugata_, _vicārānugata_, _ānandānugata_ and _asmitānugata_. True knowledge begins to dawn from the first stage of this samprajñāta state, and when the Yogin reaches the last stage the knowledge reaches its culminating point, but still so long as the potencies of the lower stages of relative knowledge remain, the knowledge cannot obtain absolute certainty and permanency, as it will always be threatened with a possible encroachment by the other states of the past phenomenal activity now existing as the subconscious. But the last stage of asamprajñāta samādhi represents the stage in which the ordinary consciousness has been altogether surpassed and the mind is in its own true infinite aspect, and the potencies of the stages in which the mind was full of finite knowledge are also burnt, so that with the return of the citta to its primal cause, final emancipation is effected. The last state of samprajñāta samādhi is called saṃskāraśesha, only because here the residua of the potencies of subconscious thought only remain and the actual states of consciousness become all extinct. It is now easy to see that no mind which is not in the ekāgra or one-pointed state can be fit for the asamprajñāta samādhi in which it has to settle itself on one object and that alone. So also no mind which has not risen to the state of highest suppression is fit for the asamprajñāta or nirvīja state. It is now necessary to come down to a lower level and examine the obstructions, on account of which a mind cannot easily become one-pointed or ekāgra. These, nine in number, are the following:— Disease, languor, indecision, want of the mental requirements necessary for samādhi, idleness of body and mind, attachment to objects of sense, false and illusory knowledge, non-attainment of the state of concentrated contemplation, unsteadiness and unstability of the mind in a samādhi state even if it can somehow attain it. These are again seen to be accompanied with pain and despair owing to the non-fulfilment of desire, physical shakiness or unsteadiness of the limbs, taking in of breath and giving out of it, which are seen to follow the nine distractions of a distracted mind described above.
