This book, Essays in Search of Understanding , covers a wide range of topics from Puzzles and Problems in Buddhism to so-called unconditional love.
Many of them are short and pithy, meant more as discussion starters than as something authoritative and final.
But all of them reflect considerable thought and inquiry.
Thoughts and lines of argument which may well both spark your own interest and further your own thinking on these topics.
But the book is not an exercise.
