[Our opponent now urges a fresh and long objection to what we have said above.] "But if we accept your definition that '_yoga_ is the suppression of the modifications of the _chitta_,' this will apply also to 'sound sleep,' since there too we may find the suppression [or suspension] of the modifications found in _kshipta_, _vikshipta_, _múḍha_,[393] &c.; but this would be wrong, because it is impossible for the 'afflictions' to be abolished so long as those states called _kshipta_, &c., remain at all, and because they only hinder the attainment of the _summum bonum_. Let us examine this more closely. For the understanding is called _kshipta_, 'restless,' when it is restless [with an excess of the quality _rajas_], as being tossed about amidst various objects which engage it. It is called _múḍha_, 'blinded,' when it is possessed by the modification 'sleep' and is sunk in a sea of darkness [owing to an excess of the quality _tamas_]. It is called _vikshipta_, 'unrestless,' when it is different from the first state[394] [as filled with the quality _sattva_]." We must here, however, note a distinction; for, in accordance with the line of the Bhagavad Gítá (vi. 34), 'The mind, O Kṛishṇa, is fickle, turbulent, violent, and obstinate,' the mind, though naturally restless, may occasionally become fixed by the transient fixedness of its objects; but restlessness is innate to it, or it is produced in it by sickness, &c., or other consequences of former actions; as it is said [in the Yoga Sútras, i. 30], 'Sickness, languor, doubt, carelessness, laziness, addiction to objects, erroneous perception, failure to attain some stage, and instability,--these distractions of the mind are called "obstacles".' Here 'sickness' means fever, &c., caused by the want of equilibrium between the three humours; 'languor' is the mind's want of activity; 'doubt' is a sort of notion which embraces two opposite alternatives; 'carelessness' is a negligence of using the means for producing meditation; 'laziness' is a want of exertion from heaviness of body, speech, or mind; 'addiction to objects' is an attachment to objects of sense; 'erroneous perception' is a mistaken notion of one thing for another; 'failure to attain some stage' is the failing for some reason or other to arrive at the state of abstract meditation; 'instability' is the mind's failure to continue there, even when the state of abstract meditation has been reached. Therefore we maintain that the suppression of the mind's modifications cannot be laid down as the definition of _yoga_.
