ज्योतिषामपि तज्ज्योतिस्तमसः परमुच्यते | ज्ञानं ज्ञेयं ज्ञानगम्यं हृदि सर्वस्य विष्ठितम्
jyotiṣāmapi tajjyotistamasaḥ paramucyate . jñānaṃ jñeyaṃ jñānagamyaṃ hṛdi sarvasya viṣṭhitam
那是光中之光；它被宣称为超越黑暗。它是知识（Jnana，吉那那），是应被知晓的（Jñeya，吉涅亚），也是知识所能达到的目标（Jñānagamya，吉那那伽米亚）。它特别安住于一切众生的心中。
That is the Light even of the lights; It is spoken of as beyond darkness. It is Knowledge, the Knowable, and the Known. It exists specially [A variant reading is dhisthitam.-Tr.] in the hearts of all.
至高“我”（Atman，阿特曼）照亮理智、心智、太阳、月亮、星辰、火焰和闪电。它是自发光的。太阳在那里不发光，月亮和星辰也不发光，这些闪电更不发光，更不用说火焰了。当它发光时，万物都随之发光，所有这些都因它的光而闪耀。（《伽陀奥义书》（Kathopanishad）5.15，亦见《白骡氏奥义书》（Svetasvataropanishad）6.14）“知识”指谦逊等美德（参见第十三章第7至11节）。“应被知晓的”如第12至17节所述。“知识所能达到的目标”即通过智慧能够理解的。这三者都安住于每个众生的心（理智，Buddhi，布迪）中。尽管太阳的光芒照耀所有物体，但在镜子等明亮洁净的物体中，太阳的光芒显得更为璀璨。同样，尽管“梵”存在于所有物体中，理智却因从“梵”那里获得的特殊光辉而闪耀。（参见第十章第20节、第十三章第3节、第十八章第61节）
The Supreme Self illumines the intellect? the mind? the sun? moon? stars? fire and lightning. It is selfluminous? The sun does not shine there? nor do the moon and the stars? nor do these lightnings shine and much less this fire. When It shines? everything shines after It all these shine by Its Light. (Kathopanishad 5.15 also Svetasvataropanishad 6.14)Knowledge Such as humility. (Cf.XIII.7to11)The knowable As described in verses 12 to 7.The goal of knowledge? i.e.? capable of being understood by wisdom.These three are installed in the heart (Buddhi) of every living being. Though the light of the sun shines in all objects? yet the suns light shines more brilliantly in all bright and clean objects such as a mirror. Even so? though Brahman is present in all objects? the intellect shines with special effulgence received from Brahman. (Cf.X.20XIII.3XVIII.61)
