5.27-28 Sparsan etc.;  Yatendriya-etc. Warding  off outside,  i.e.,  not accepting, the external contacts (objects);  establishing all the sense-organs - indicated by  'sense of  sight' - in the middle place in between the two wandering ones, i.e.,  the right and the left views in the form of desire and wrath  viz., in that particular place which is free from both these;  he would remain fixing  in eipoise  (or making neutral)  both the forward  (upward) and  backward  (downward)  moving forces  viz., the pious and impious acts,  within the mental modification.  Nasa  'that  which acts crookedly'.  This is mental modification,  because it behaves crookedly i.e.,  ineally due to  anger etc.  The same is in the external plane.  A man of Yoga  of  this type is just free, though he transacts all mundane business.
