Chapter VI · Śloka 11
शुचौ देशे प्रतिष्ठाप्य स्थिरमासनमात्मनः |
नात्युच्छ्रितं नातिनीचं चैलाजिनकुशोत्तरम् ||
नात्युच्छ्रितं नातिनीचं चैलाजिनकुशोत्तरम् ||
śucau deśe pratiṣṭhāpya sthiram āsanam ātmanaḥ |
nāty-ucchritaṃ nāti-nīcaṃ cailājina-kuśottaram ||
nāty-ucchritaṃ nāti-nīcaṃ cailājina-kuśottaram ||
In a clean place one should establish a firm seat for oneself — neither too high nor too low — covered with kuśa grass, a deer skin, and cloth, one upon the other.
The detailed specification of the meditation seat grounds the teaching in practical reality. Cleanliness of place, stability of posture, appropriate height — these are not mere ritual conventions but the material conditions that allow the body to become still enough for the deeper work to begin.
