674. Right knowledge (samyak-jnan) means and includes the knowledge of the nature of self and non self that is the free of three types of wrong knowledge (Mithya-Jnan) i.e. Doubtfulness (Sainshaya/scepticism). Adversity (Viparyaya/vimoha) and (Vibhrama/anadhya) right knowledge explains the real/natural or soul. Hence it has been designated as positive (Sakar) or definite (Savikarpak). It is of many kinds.
675. Knowledge is of five kinds: 1. Sensory; 2. Scriptural (Srit-Jnan); 3. Clairvoyance; 4. Telepathic and 1. Perfect knowledge (Keval jnan).
676 Thus knowledge (Jnan) is of five kinds: Sensory, Scriptural, Clairvoyance, Telepathic and perfect of these five, the first four destructive subsidential operational (Kshayopashimk); the last one (i.e. perfect knowledge) is destructive (Kshayik). (The first four are incomplete because they arise out of the destruction subsidence of or operation of karmas partly; the fifth is perfect (Complete), because it arises out of the destruction of all karmas in toto).
677. The sensory knowledge means and includes conception (iha) Judgment (apoha), perception (mimansa), margana), recognition (samjna) shakti, sensitivity (mati), and Judicious or discrete knowledge.
678 (Like Reasoning by inference/Anuman/linga-jnan), the scriptural knowledge consists of knowing or grasping the clear meaning expressed in words (Vacyartha) on the basis of the knowledge of words of “Arhat’s” (Sabda/Arhta). This knowledge is as a rule the result of sensory knowledge (Abhinibodhak/Matijnan). The scriptural knowledge is of two kinds: 1. Verbal (Sadba-janya) and 2. Non-verbal (to know about fire by seeing smoke in the sky is nonverbal scriptural knowledge and the knowledge derived from works read or spoken is verbal scriptural knowledge). Again there is predominance of verbal scriptural knowledge.
679. The scriptural knowledge has been so denominated as it follows the scriptures with the help (support) of senses and mind. It is capable of communicating the significance (purpose) of its subject (visaya bhuta Artha). The rest (i.e. the tendency towards an object (Avagrega) and the like knowledge which is not in accordance with scriptures, though it caused by senses and mind, is sensory knowledge (Mati-jnan).
680. The sensory knowledge includes (Precedes and assists) the scriptural knowledge; not vice versa. This is the main difference in between these two kind of knowledge. The word “Purva” has been derived from the root (dhatu) “pri” which means fastening up/complying with/palan and completing/filling/purana. As the sensory knowledge completes and complies with scriptural knowledge it (sensitive-knowledge) precedes it (scriptural) (knowledge). Hence, scriptural knowledge has been said to be mingles with sensory knowledge.
681. “Avadhiyati” its avadhih (i.e. the knowledge, which partly know the objects having limitations of subjects matter (Dravya), area/space (kshetra), time (kala) and quality of the objects known (Bhava) is called clairvoyance knowledge (Avadhi-Jnan). Agama describes it as the knowledge limitation. It is of two kinds: 1. The clairvoyance knowledge since birth (Bhava-pratyaya) and 2. The clairvoyance knowledge derived from merit (Guna pratyaya).
682. The knowledge which directly knows the thoughtful (chintiata), unthoughtful (Achintita) and semi thoughtful (Ardha-chintita) minds of embodied souls of the human universe (Maunsya-lok) is called telepathic knowledge (Manah-parayaya) (Jnan).
683. The word “Keval” signifies one (Eka) pure (Shuddha) Gross (sakal) extra ordinary (Asadharana) and infinite (Ananta). Hence perfect knowledge (keval-Jnan) one it is not assisted (or supported) by senses etc.; and all the other kinds of knowledge disappear (retire) the moment it manifests. Therefore perfect knowledge is alone (E’ka ki/singular) and is pure by virtue of that being (absolutely) free of all the spots/flaws of the filth (of karmas). It is gross, as it knows (understands) all the knowables. It is extra-ordinary; because there is no parallel or comparison to it (none other forms of knowledge is a match of/equal to it). It is infinite because it never ends.
684. Perfect knowledge knows universe and non universe in all its totality. There was nothing in past and noting at present and shall be nothing in future, which perfect knowledge does not know.
685. Pramana is the knowledge which rightly knows the nature of soul (Vastu-svabhava). It is of two kinds : 1. Direct and 2. Indirect
686. The soul (jiva) is called “Akasha” this word has been derived from the root (Dhata) “Ashuvyapn”. “Akasha” (Jiva) is that which is prevailing (vyapta) in all the beings in the form of knowledge the derivation of the work “Akasha” can also be effected for the root “Ash” that means food. He who enjoys the prosperity of all the three worlds is “Aksha” (Jiva). In this way the interpretation of Juva as Aksha is done from both roots, The knowledge obtained through “Akasha” is direct (Pratyaksha) is if three kinds: 1. Clairvoyance, 2. Telepathic and 3. Perfect.
687. The objective senses (Dravyendriya’s) and the mind (mana) are different from “Aksha” (Jiva). Hence the knowledge acquired thorough them is called indirect (paroksa). Just as in inference (Anuman) the smoke gives the knowledge of fire in the same way the indirect knowledge is caused by non self (par/other).
688. The sensory and scriptural knowledge of the soul (jiva) are indirect (Apratyaksha) by virtue of being dependent upon others because they are caused by the remembrance of an object known before (but which is now out of sight), as in inference.
689. The scriptural knowledge which is caused by the signs (linga) such as smoke etc. is a parial manner (Ekant rupame) definitely indirect. The clairvoyance, telepathic and perfect (Ekant-rupa se pratyaksh). The sensory knowledge that is acquired by the external help of sense organs and mind is considered as a worldly behaviour (lok vyavahar). Hence it is called “Practically In direct” (sanivyavaharika) (pratyaksha).
