28th Sutra Chapter 2
योगाङ्गाऽनुष्ठानादशुद्धिक्षये ज्ञानदीप्तिराविवेकख्यातेः
yogangganushthanad ashuddhikshaye jnanadiptira vivekakhyateh
* yoga-angga - limbs of yoga
* anushthanad - by the practice
* ashuddhi - impurities
* kshaye - destroyed
* jnana - knowledge
* diptih - shining, effulgent
* a - until, up to
* viveka-khyateh - discriminative knowledge.
When the limbs of yoga are practiced, impurities dwindle, and the light of wisdom dawns leading to discriminative discernment.
