Is There a Reality You Can Never Access Through Your Senses?

Kant drew a line at the noumenon. The Kena Upanishad crossed it.

Kena Upanishad vs Kant. Both agree the senses have limits. They disagree on whether you can go beyond them.

The Blade of Grass

The gods had just won a battle. Their army had scattered the asuras across the plain, and now the devas stood together in the afterglow of victory, congratulating each other for the strength of their arms. Agni, the god of fire, was there. Vayu, the god of wind, was there. Indra, king of the gods, stood tallest among them. They had not quite gotten around to asking whose power had actually won the battle, because they assumed they knew.

That is when the presence appeared before them. The Kena Upanishad calls it simply a yakṣa, a mysterious figure of dazzling form that none of the gods recognized. Indra sent Agni forward to investigate.

The yaksha looked at Agni. 'What is your power?' it asked. 'I can burn anything in this world,' said Agni. The yaksha placed a single dry blade of grass on the ground between them. 'Burn this.'

Agni came at the blade with the full force of the fire that warms the sun. He could not burn it. He tried again, harder. Nothing. The blade lay on the ground, untouched, as though fire had no meaning in its presence. Shamed, Agni returned to the others.

Vayu tried next. 'What is your power?' 'I can blow anything in this world off its feet.' The yaksha pointed at the same blade of grass. 'Blow this away.' Vayu could not move it. Not a rustle. He returned, shamed.

Only when Indra himself went forward did the yaksha withdraw from view, and the goddess Uma appeared in its place to explain what the gods had just met. The blade was not magic. The yaksha was Brahman, the awareness that lets fire burn and wind blow in the first place. That, Uma said, is the power by which you defeated the asuras. You mistook it for your own.
