II, 61] PRAVACANASĀRA,
19 54. Life-essentials of Jīvas or souls are senses, bala' (ie, the channels of activities ), duration of life and respiration,
*3. Life-essentials ( in details ) are ten: five senses, three channels of activity viz., of mind, speech and body, respiration and the duration of life.
.55. That which formerly lived, lives now and will live in future with the four life-essentials is the Jīva, the sentient principle; these lifeessentials, moreover, are fashioned by material substances.
56. The soul endowed with life-essentials, bound by infatuatory and other Karmas, and enjoying the fruit of Karmas, is bound by other additional Karmas.
57. If the Jīva, through delusion and hatred, causes harm to the life-essentials of living beings, this results into the bondage of Karmas such as knowledge-obscuring.
58. The soul tainted with Karma, so long as it does not give up attachment towards external objects the foremost of which is the body, possesses other life-essentials again and again.
59. He, who has conquered his senses etc. and meditates the pure manifestation of consciousness of his self, will not be tainted by Karmas; how then can the life-essentials follow him ? :
. 60. The transformation of one condition into another, in the case of the soul (when coming into contact with matter) whose existential nature is already) determined, is the modification with its varieties of figuration etc.
61. Human; hellish, sub-human and divine modifications of the soul are mutually different with regard to the figuration (of the body) etc., because of the operation of Nāma-karman.
1. The life-essentials do not form the nature of the soul-stuff, but they are the indications or the signs of the presence of the soul in an embodied condition. We do not perceive the soul, but it has certain essential features in this mundane existence; and they are four in number (and the same would be ten when their details are taken into consideration). The four life-essentials are typically selective and mutually exclusive to a great extent. The signs of soul given by Vais'eşikas, namely, prānapāna-nimisonmeşa-jīvanamano-gatindriyantara-vikäräh sukha-duhkhecha-dvesa-prayatnās'catmano lrngāni (V. S. III, 2, 4), look more like a descriptive enumeration.
