सर्वस्य चाहं हृदि सन्निविष्टो
मत्तः स्मृतिर्ज्ञानमपोहनं च।
वेदैश्च सर्वैरहमेव वेद्यो
वेदान्तकृद्वेदविदेव चाहम्।।15.15।।
15.15 And I am seated in the hearts of all; from Me are memory and knowledge, as well as their absence. I am verily That which has to be known by all the Vedas; I am indeed the author of the Vedanta and the knower of the Vedas am I.
15.15 And aham, I, as the Self; san-nivistah, am seated; hrdi, in the hearts, in the intellects; sarvasya, of all creatures. Therefore, with regard to all the creatures, mattah, from Me, from the Self; are Smrtih, memory; jnanam, knowledge; and their apohanam, loss. The knowledge and memory of these creatures who perform good deeds come from Me in accordance with the good deeds; similarly, the loss, deterioration, of memory and knowledge of those who perform evil deeds comes from Me in accordance with the evil deeds. Aham eva, I alone, the supreme Self; am the vedyah, object to be known; sarvaih, through all; vedaih, the Vedas. I am also the vedanta-krt, the originator of the Vedanta, i.e., the source of the traditional school of the teachings of Vedanta; and aham eva, I Myself; am the veda-vit, knower of the Vedas, the knower of the teachings of the Vedas. In the verses beginning with, That light in the sun which৷৷. (12), etc. have been stated briefly the majesty of God, the Lord called Naravana, which arise from special limiting adjuncts. Now then, the succeeding verses are begun with a view to determining the real nature of that very Lord as the Unconditioned and Absolute, by distinguishing Him from the limiting adjuncts, (viz) the mutable and the immutable. In that connection, after dividing into three parts [The two limiting adjuncts-the mutable and the immutable-, and the supreme Self.] all the teachings of the preceding and the immediately succeeding chapters, the Lord says:
Sarvasya chaaham hridi sannivishtoMattah smritir jnaanam apohanam cha; Vedaischa sarvairahameva vedyoVedaantakrid vedavid eva chaaham.
sarvasya—of all living beings; cha—and; aham—I; hṛidi—in the hearts; sanniviṣhṭaḥ—seated; mattaḥ—from Me; smṛitiḥ—memory; jñānam—knowledge; apohanam—forgetfulness; cha—as well as; vedaiḥ—by the Vedas; cha—and; sarvaiḥ—all; aham—I; eva—alone; vedyaḥ—to be known; vedānta-kṛit—the author of the Vedānt; veda-vit—the knower of the meaning of the Vedas; eva—alone; cha—and; aham—I
