The works of Ādi Śaṅkarācārya

Svātmaprakāśikā

Verse 63

सूक्ष्मनाडीषु संचारो बुद्धेः स्वप्नः प्रजायते ।संचारधर्मरहिते स्वप्नो नास्ति तथा मयि ॥ ६० ॥

In plain words

When the buddhi travels through the subtle channels, dreaming is born. Where there is no attribute of movement, there is no dream — and so there is none in me.

Close to the Sanskrit

The movement of the intellect in the subtle channels — from that, dream is born. In that which is devoid of the attribute of movement, dream does not exist; and so it is in me.
