c10.s5.t3.9

(2) At death, according to Chând. 6. 8. 6,¹ speech enters into manas, manas into prâṇa, prâṇa into tejas, tejas into the supreme godhead. Just as here by speech all the indriyas are apparently intended, so by tejas we seem to be obliged to understand all the three primeval elements (tejas, âpas, annam, of which indeed, according to Chând. 6. 5. 4, speech, prâṇa and manas consist), which, as we shall see later, have been developed into prakṛiti with its three guṇas.
