Sādhana Pāda · Sutra 48

ततो द्वन्द्वानभिघातः

tato dvandvānabhighātaḥ

Then, the pairs of opposites cease to affect.

When āsana is mastered according to the previous sutras, the yogi ceases to be disturbed by the dvandvas, the pairs of opposites.

Cold and heat, pleasure and pain, hunger and satiety, praise and criticism: these polarities that normally shake the mind lose their power.

Anabhighāta means “without blow,” “without being disturbed.” It’s not insensitivity, but equanimity. Sensations are registered but don’t destabilize.

This is a siddhi of perfect āsana: liberation from the tyranny of external conditions.

It also prepares for higher practices. A meditator who jumps at every discomfort cannot go deep. The stability of the body produces stability of the mind.
