नियमसार
The substance of medium of motion - dharma - renders assistance to souls and matter in their state of motion, just as water assists aquatic animals in their motion; it does not cause them to move if they are stationary.
ठाणजुदाण अधम्मो पुग्गलजीवाण ठाणसहयारी । छाया जह पहियाणं गच्छंता णेव सो धरई ॥१८॥ ठहराव-सहित जो पुद्गल और जीव हैं, उनके ठहरने में सहकारी कारण अधर्म-द्रव्य है; जैसे पथिकों (बटोहियों) की ठहरने की स्थिति में छाया सहकारी है। और गमन करते हुए जीव तथा पुद्गलों को वह अधर्म-द्रव्य नहीं ठहराता है।
The substance of medium of rest – adharma - renders assistance to souls and matter in their state of rest, just as the shade (of a tree, etc.) assists travellers in their state of rest; it does not hold them back if they are moving.
Space (ākāśa) has infinite space-points and it pervades both the universe (lokākāśa) and the non-universe (alokākāśa). The division of this infinitely expansive space (ākāśa) which accommodates the souls (jīva), the matter (pudgala), the medium of motion (dharmāstikāya), the medium of rest (adharmāstikāya), and the time (kāla), is the universe-space (lokākāśa). In the infinite space (ākāśa) beyond, these five substances do not permeate; this is the non-universe-space (alokākāśa).1

आकाशस्यावगाहः ॥५-१८॥
समस्त द्रव्यों को अवकाश - स्थान - देना, यह आकाश द्रव्य का उपकार है।
