वृत्तयः पञ्चतय्यः क्लिष्टाक्लिष्टाः
At one level this sūtras refers to simple experiences - a beautiful sunset, freshly cut grass, road-kill, the living dead; or even neutral experiences - stirring tea, combing one's hair. Interestingly what is pleasurable for one person, may not be so for another. Not everyone loves the opera, blue cheese and wasabi. There are people who don't like dogs or are downright scared of them. The reason for these individual reactions is treated later in the sūtras. But it bears reflection at this stage.
