The mind, says Vasubandhu, is called cittam, because it wills (_cetati_), manas because it thinks (_manvate_) and vijñâna because it discriminates (_nirdis'ati_). The discrimination may be of three kinds: (1) svabhâva nirdes'a (natural perceptual discrimination), (2) prayoga nirdes'a (actual discrimination as present, past and future), and (3) anusm@rti nirdes'a (reminiscent discrimination referring only to the past). The senses only possess the _svabhâva nirdes'a_, the other two belong exclusively to manovijñâna. Each of the vijñânas as associated with its specific sense discriminates its particular object and perceives its general characteristics; the six vijñânas combine to form what is known as the Vijñânaskandha, which is presided over by mind (_mano_). There are forty-six caitta sa@msk@rta dharmas. Of the three asa@msk@rta dharmas âkâs'a (ether) is in essence the freedom from obstruction, establishing it as a permanent omnipresent immaterial substance (_nîrûpâkhya_, non-rûpa). The second asa@msk@rta dharma, apratisa@mkhyâ nirodha, means the non-perception of dharmas caused by the absence of pratyayas or conditions. Thus when I fix my attention on one thing, other things are not seen then, not because they are non-existent but because the conditions which would have made them visible were absent. The third asa@msk@rta dharma, pratisa@mkhyâ nirodha, is the final deliverance from bondage. Its essential characteristic is everlastingness. These are called asa@msk@rta because being of the nature of negation they are non-collocative and hence have no production or dissolution. The eightfold noble path which leads to this state consists of right views, right aspirations, right speech, right conduct, right livelihood, right effort, right mindfulness, right rapture [Footnote ref 1]. ___________________________________________________________________ [Footnote 1: Mr Sogen mentions the name of another Buddhist Hînayâna thinker (about 250 A.D.), Harivarman, who founded a school known as Satyasiddhi school, which propounded the same sort of doctrines as those preached by Nâgârjuna. None of his works are available in Sanskrit and I have never come across any allusion to his name by Sanskrit writers.] 125 Mahâyânism.
