3.323

有名曰：經稱法身已上入無為境，心不可以智知、形不可以象測，體絕陰入、心智寂滅。而復云，進修三位，積德彌廣。

The Named states: The sūtras state that from the Dharma-body onward one enters the unconditioned realm, where the mind cannot be known through wisdom and the form cannot be measured through imagery; its essence is severed from skandhas and āyatanas, and mind and wisdom are quiescent and extinct. Yet it is also said that one advances in cultivating the three stages and accumulates virtues ever more broadly.
