Yoga Sūtras

Or, the mind becomes steady by resting in insight from dreams or deep sleep.

Deep sleep is a mental activity based on the absence of content.

Disturbances that distract the mind and block the path include sickness, mental laziness, doubt, carelessness, physical laziness, craving, confusion, lack of progress, and lack of consistency

The posture should be steady and comfortable

These ethical commitments constitute the Great Vow of yoga: universal, timeless, and unconditional, applicable to everyone in every place at every time regardless of role or situation.

With the removal of ignorance, our true nature is revealed. This is the absolute freedom of the seer.

Or by focusing the mind on thoughts free from attachment.

Imagination comes from words devoid of substance

The phenomenal world consists of material elements and senses characterized by their illumination, activity, and inertia. This world can serve the goals of sensual experience or spiritual liberation.
