tato muñjād iṣīkeva śakuniḥ pañjarād iva |
kṣetra-jño niḥsto dehān mukta ity abhidhīyate || 12.64
Thus, like the stalk from a sheath of muñja grass,
Like a big bird from its cage,
The Knower of the Field, escaped from the body,
Is said to be liberated.
Saccharum bengalense is said to be a very large tufted grass which is of little account as a fodder plant since cattle and buffaloes will only eat the tender young leaves.
And śakuni means any bird but especially a large one.
So Arāḍa seems to be indicating, as a relatively big deal, an event when one thing separates from another.
In the simile of the muñja grass, the stalk and the leaf-sheaths originally belong to the same plant; but in the simile of the bird and the cage, the bird is animate and the cage is inanimate.
In today's verse, then, there seems to be no ambiguity about it. Arāḍa's teaching at this point goes against the principle of psychophysical unity.
Right here, in this separation, is the point of divergence between Arāḍa's teaching and what will be the teaching of the fully awakened Sambuddha. In the realization of the former, as Arāḍa conceives it, the spiritual is prioritized at the expense of the material, from which the spiritual escapes. In the realization of the latter, as Aśvaghoṣa describes it, the earth shakes and gods rejoice.
