One by whom the world is not disturbed, and who is not disturbed by the world, free from excessive joy, impatience, fear and anxiety — that one is also dear to Me.

This verse describes a notable reciprocity: the yogī doesn’t disturb the world (na udvijate lokaḥ) and the world doesn’t disturb them (lokāt na udvijate). It is an ecology of peace.

The first half suggests that the yogī’s presence is calming, not agitating. They don’t generate conflict or anxiety in those around them. Their practice benefits not only themselves but the environment.

Four disturbances are mentioned:

• Harṣa — excessive joy (excitement)
• Amarṣa — impatience, irritation
• Bhaya — fear
• Udvega — anxiety, agitation

Mukta (free) indicates that these emotions may arise but don’t capture the yogī. It’s not insensitivity but non-identification with emotional states.

This emotional balance is the fruit of sustained practice. Haṭha Yoga works on this from the body: regulated breathing calms anxiety; stable āsanas cultivate physical equanimity that translates into mental.
