The Knowledge Concerning the Immutable Brahman

The higher knowledge relates to the Immutable Brahman, as noted in verses 6 and 7 of the 1st section of chapter 1 of the Mundaka Upanishad, as translated by Sri Aurobindo:

“That the invisible, that the unseizable, without connections, without hue, without eye or ear, that which is without hands or feet, eternal, pervading, which is in all things and impalpable, that which is Imperishable, that which is the womb of creatures sages behold everywhere.  As the spider puts out and gathers in, as herbs spring up upon the earth, as hair of head and body grow from a living man, so here all is born from the Immutable.”

The Upanishads use a lot of “negative” attributes to describe the Immutable Brahman, in order to avoid the mind fixing on a specific characteristic and thereby trying to limit the Brahman by that characteristic.  The positive characteristics that express the unlimited nature of the Brahman are immediately associated.  The Brahman transcends all created objects and forces, it acts as their container, their womb, and their content.

The images of the spider, the herbs and the hair all illustrate how the  manifested universe is based on and is created by, and from, the Immutable Brahman.  They are not separate or independent, but actually embody the Brahman in form, without thereby limiting the Brahman in its all-pervasive, infinite and Immutable form.

The Upanishads make it clear that we cannot grasp the Immutable with our minds or our words.  They also make it clear that there is no duality: “one without a second” and that the names, forms, and energies that go into the world we live in are manifestations of that sole Existent:  “all this is the Brahman.”

The Lower and the Higher Knowledge As Described by the Mundaka Upanishad

The Mundaka Upanishad first describes for Saunaka the elements of the lower knowledge and then contrasts this with the higher knowledge.  The lower knowledge represents the means of action and success in the outer world.  One can attain all one’s desires and achieve states of heavenly enjoyment through proper understanding of the Vedas and related sciences.  Yet all of these results are transitory and to some degree illusory as they come, and then they go.  The higher knowledge is permanent and is the knowledge of the Supreme, the Absolute, the Unchanging.

Verse 5 of Chapter 1, Section 1 of the Mundaka Upanishad:  “Of which the lower, the Rig-Veda and the Yajur-Veda, and the Sama-veda and the Atharva-veda, chanting, ritual, grammar, etymological interpretations, and prosody and astronomy.  And then the higher by which is known the Immutable.”

The Vedic knowledge and the various other sciences are essential for worldly action, and to some degree, the concentration or focus involved develops the faculties and prepares them for the next step of human development.  The seeking after the higher knowledge of the Immutable requires deep concentration and the tools developed in what is known as Jnana Yoga are based initially on powers developed through the concentration on the Vedic texts and their application in action, including chanting, rituals, and various sacrificial forms which are not to be taken solely in the restricted sense of religious rituals, but in the sense of the dedication of one’s time, energy, and focus on spiritual truths of existence, and the implementation of these principles in outer action of all kinds.  It is true that in certain phases of development, Vedantic practitioners and scholars have limited the scope to observance of religious rituals, but apparently the intended scope was wider and encompassed all of the life activities.  This is one significance of the teaching being given to a “house lord” in this Upanishad, to remind the seekers that this knowledge is not restricted solely to those who have dedicated themselves to a religious life of abstention and one-pointed exclusive concentration.
