1. Glory (yaśas) be with us two ! Pre-eminence in sacred knowledge (brahma-varcasa) be with us two !

Now next, we will expound the mystic meaning (upaniṣad) of combination (saṃhitā) in five heads: with regard to the world; with regard to the luminaries; with regard to knowledge; with regard to progeny; with regard to oneself.

Now, with regard to the world.— The earth is the prior form; the heaven, the latter form. Space is their conjunction; wind, the connection.—Thus with regard to the world.

1.3.2

vāyuḥ sandhānam /

āditya uttararūpam /
āpaḥ sandhiḥ /

ityadhijyautiṣam /
athādhividyam /
ācāryaḥ pūrvarūpam // 2//

Now, with regard to the luminaries.— Fire is the prior form; the sun, the latter form. Water is their conjunction; lightning, the connection.—Thus with regard to the luminaries.

Now, with regard to knowledge.— The teacher is the prior form; the pupil, the latter form. Knowledge is their conjunction; instruction, the connection.—Thus with regard to knowledge.

1.3.3

Now, with regard to progeny.— The mother is the prior form; the father, the latter form. Progeny is their conjunction; procreation, the connection.—Thus with regard to progeny.

1.3.4

4. Now, with regard to oneself.— The lower jaw is the prior form; the upper jaw, the latter form. Speech is their conjunction; the tongue, the connection.—Thus with regard to oneself.

These are the great combinations. He who knows these combinations thus expounded, becomes conjoined with offspring, with cattle, with pre-eminence in sacred knowledge, with food, with the heavenly world.
