Jīva, in two, in three, in four, and lastly in five ways. v. Six classes.We now come to the six ways in which Jīva may be divided, namely, into Pṛithvīkāya, Apakāya, Teukāya, Vāyukāya, Vanaspatikāya, and Trasakāya. Of these we have studied earth, water, fire, wind and vegetable lives, so it only remains for us to look at Trasakāya. The Jaina say that in the class of Trasakāya are included all lives that have the power of motion and which, when swayed by trāsa (dread), can try and get out of danger. All lives possessing two or more indriya are included under this heading as Trasakāya or mobile, whilst earth, water, fire, air and vegetable are considered immobile.
vi. Seven classes.Again, Jīva may be classified in seven ways: hell beings (which are all neuter!), male lower animals, female lower animals, male human beings, female human beings, male demigods and female demigods.
vii. Eight classes.This last is perhaps a somewhat artificial classification introduced for the sake of symmetry, but when we come to the next series, where Jīva is divided into eight classes, we touch on one of the most important points in Jaina philosophy, and one which it shares with the followers of Gośāla. The Jaina say Jīva may be divided into eight classes according to the six Leśyā[1] by which it is swayed, and according to whether it is swayed by any emotion or not.[2] These emotions affect the colour of the soul they govern just as a crystal is coloured by the hue of the substance on which it rests.
vii (a).Beings in the first class, or Saleśī, include all who are yet swayed by any of the three good or three bad emotions.
vii (b).Kṛiṣṇaleśyā is the worst of the three bad emotions, and it is described as being black as a thunder-cloud, bitter as a Neem tree, smelling like a dead cow, and rougher
