अर्जुन उवाच | प्रकृतिं पुरुषं चैव क्षेत्रं क्षेत्रज्ञमेव च | एतद्वेदितुमिच्छामि ज्ञानं ज्ञेयं च केशव
arjuna uvāca . prakṛtiṃ puruṣaṃ caiva kṣetraṃ kṣetrajñameva ca . etadveditumicchāmi jñānaṃ jñeyaṃ ca keśava
阿周那說：「喔，凱沙瓦，我願知曉原質（Prakriti）與神我（Purusha），場域（Kshetra）與場域知者（Kshetrajna），以及知識（Jnana）與應知者（Jneya）。」
Swami Gambhirananda has not translated this sloka. Many editions of the Bhagavadgita do not contain this sloka, including the commentary by Sankaracharya. If this sloka is included, the total number of slokas in the Bhagavadgita is 701.
此節為《薄伽梵歌》第十三章的開篇，阿周那向克里希那提問，希望深入了解原質（物質）與神我（精神）、場域（身體）與場域知者（靈魂），以及知識與應知者之間的區別。這標誌著《薄伽梵歌》第三部分的開始，重點探討辨別智慧（Jnana Yoga）的道路。
In some of the books you will not find this verse. If you include this verse also? the number of verses of the Bhagavad Gita will come to 701. Some commentators look upon this verse as an interpolation.We have come to the beginning of the third section of the Gita. Essentially the same knowledge is taught in this section but there are more details.This discourse on Kshetra (matter) is commenced with a view to determine the essential nature of the possessor of the two Prakritis (Natures)? the lower and the higher? described in chapter VII? verses 4 and 5.In the previous discourse a description of the devotee who is dear to the Lord is given from verse 13 to the end. Now the estion arises What sort of knowledge of Truth should he possess The answer is given in this discourse.Nature is composed of the three alities. It transforms itself into the body? senses and the sensual objects to serve the two purposes of the individual soul? viz.? Bhoga (enjoyment) and Apavarga (liberation).The Gita is divided into three sections illustrative of the three words of the Mahavakya or Great Sentence of the Sama Veda -- TatTvamAsi (That thou art). In accordance with this view the first six chapters deal with the path of action or Karma Yoga and the nature of the thou (TvamPada). The next six chapters explain the path of devotion or Bhakti Yoga and the nature of That (TatPada). The last six chapters treat of the path of knowledge or Jnana Yoga and the nature of the middle term art (AsiPada) which establishes the identity of the individual and the Supreme Soul (Jiva Brahma Aikyam).Arjuna now wishes to know in detail the difference between Prakriti and Purusha (Matter and Spirit). He desires to have a discriminative knowledge of the difference between them.
