Patanjali Yoga Sutra 2.15
Sanskrit Sutra
परिणामताप-संस्कारदुःखैर्गुणवृत्तिविरोधाच्च दुःखमेव सर्वं विवेकिनः॥१५॥
Swami Vivekananda's translation
To the discriminating, all is, as it were, painful on account of everything bringing pain either as consequence, or as anticipation of loss of happiness, or as fresh craving arising from impressions of happiness, and also as counteraction of qualities.
