Here’s a taste of the profound and beautiful symbolism of the Rig Veda.
Rig Veda, Maṇḍala 10, Hymn 90. Puruṣha.
1. A thousand heads hath Puruṣha, a thousand eyes, a thousand feet. | On every side pervading earth he fills a space ten fingers wide. || 2. This Puruṣha is all that yet hath been and all that is to be; | The Lord of Immortality which waxes greater still by food. || 3. So mighty is his greatness; yea, greater than this is Puruṣha. | All creatures are one-fourth of him, three-fourths eternal life in heaven. || 4. With three-fourths Puruṣha went up: one fourth of him again was here. | Thence he strode out to every side over what eats not and what eats. || 5. From him Virāj was born; again Puruṣha from Virāj was born. | As soon as he was born he spread eastward and westward o’er the earth. || 6. When Gods prepared the sacrifice with Puruṣha as their offering, | Its oil was spring, the holy gift was autumn; summer was the wood. || 7. They balmed as victim on the grass Puruṣha born in earliest time. | With him the Deities and all Sādhyas and Ṛiṣhis sacrificed. || 8. From that great general sacrifice the dripping fat was gathered up. | He formed the creatures of the air, and animals both wild and tame. || 9. From that great general sacrifice Ṛichas and Sāma-hymns were born: | Therefrom were spells and charms produced; the Yajus had its birth from it. || 10. From it were horses born, from it all cattle with two rows of teeth: | From it were generated kine, from it the goats and sheep were born. || 11. When they divided Puruṣha how many portions did they make? | What do they call his mouth, his arms? What do they call his thighs and feet? || 12. The Brahman was his mouth, of both his arms was the Rājanya made. | His thighs became the Vaiśya, from his feet the Śūdra was produced. || 13. The Moon was gendered from his mind, and from his eye the Sun had birth; | Indra and Agni from his mouth were born, and Vāyu from his breath. || 14. Forth from his navel came mid-air; the sky was fashioned from his head | Earth from his feet, and from his ear the regions. Thus they formed the worlds. || 15. Seven fencing-sticks had he, thrice seven layers of fuel were prepared, | When the Gods, offering sacrifice, bound, as their victim, Puruṣha. || 16. Gods, sacrificing, sacrificed the victim: these were the earliest holy ordinances. | The Mighty Ones attained the height of heaven, there where the Sādhyas, Gods of old, are dwelling.
