Sawaki Roshi: Everyone steeps himself in his own life or lives, blindly believing that there must be something to his daily activity. But in reality, a human being's life does not differ from a swallow's, the males collecting food and the females hatching eggs.
Uchiyama Roshi: This is the season swallows are flying about. People working in the shadow of tall buildings in the city probably miss seeing swallows hatching in the spring. It's a lovely site to see them during spring and summer, isn't it? Some people just get by in life, live from day to day, and never see their lives as a whole. Kobo-Daishi(774-835, the founder of the Shingon Sect) called them Ishoteiyoshin, a flock of stray sheep.
