8: The four sub-divisions of desire should be studied in the Brahmana of the Sama-veda.  (1) The desire to know; whence (2) the desire to possess; thereafter (3) the desire to secure possession, i.e., to take the necessary steps, the action, that will bring possession; and finally (4) the attainment—these respectively are the four sub-divisions, cognitive-desire, desire-proper, active-desire and summation-desire.
"The ruler of desire is Shiva and his instruction to his sub-hierarchs takes this shape:  Behold, our work is the work of destruction.  The order and the way thereof are these.  This should be destroyed first, this afterwards; and such and such work of the nature of negation should be performed.  First, make enquiry, entertain the 'desire to know,' and thoroughly and fully understand the nature of the I and the This.  Then entertain the desire to possess, 'I shall obtain the This and the I.'  Having obtained them, you will pass on to the Negation, to the declaration, 'no (I want them no more).'  In the Negation is the summation, sam-a-hara, 'bringing all together,' and it is the sam-hara also, the 'taking all in,' re-absorption, destruction."—Pranava-Vada, p. 364.
