Srimad Bhagavad-Gita :
Chapter-13. ( Kshetra-kshetrajna-vibhaga-yogam )
Slokam-1. ( Arjuna question to Lord Sri Krishna ) -
(Arjuna said: O Lord, I wish to know about prakrti [nature], Purusha [the experiencer], and the field and the knower of the field, and of knowledge and the end of knowledge. )
prakrtim purusham caiva kshetram kshetragjnameva ca,
etadveditumicchami jnanam jneyam ca kesava.
arjuna uvaca = Arjuna said;
kesava! = O Lord;
prakrtim purusham ca eva = nature, and the experiencer;
kshetram kshetragjnam ca eva = kshetram (body), and kshetragjnan ( jivatma );
jnanam jneyam ca etat = jnanam ( knowledge ), jneyam ( object of the knowledge, all about these;
veditum icchami = I wish to know.
To assert the indisputably modifiable and perishable physical body and its qualitative characteristics to the immortal atma in accordance with the law of coexistence of subject and attribute is as unreasonable as asserting that the milk of cattle is an inseparable attribute of every type of cow, bull or heifer falling under that generic term.
Due to the fact that the phenomenally unique and sublime nature of the atma precludes any perceptibility by the senses of sight, sound, taste, touch and smell to experience it and is only perceptible by the consciousness of a clarified mind purified by introspection amd meditation derived from the process of yoga or the science of the individual consciousness perfecting communion with the ultimate consciousness.
The spiritually deficient are beguiled and bewildered by the mere propensity of matter and deluded misconstrue the perishable physical body and the eternal, immortal atma. This will be further clarified in chapter 15, verses 10 and 11 where Lord Krishna explains that those bereft of wisdom with impure thoughts cannot perceive the atma.
