Yoga sutra 2.10
te prati-prasava-heyāḥ sūkṣmāḥ
When those sources of suffering are subtle such afflictions must be minimized by examining their source
When these sees of torment exist in subtle forms, all seems well, but the afflictions may suddenly grow and envelop you. Therefore, now is not the time to be lazy. Take advantage of calmer times and seize the opportunity to work further on yourself. Afterall, you cannot mend a sail in stormy weather.
