Consider one thing. If a person is living happily, no one asks him, ‘Say, friend, how is it you are happy?’ But if he is sorrowful, everyone pours down a shower of questions: ‘Why, friend, are you sorrowful?’ Why? Man has happiness as his svabhāva, so it causes no surprise. Sorrow, on the other hand, is contrary to man's svabhāva, so it causes great surprise and draws many questions. Sorrow is formed through delusion; it is not ours by nature. That is why all distortions arise.
