Here are two key phrases from Bashô-related texts on the subject of travel and haikai. In both cases, fûga is basically synonymous with haikai.
1. 東海道の一筋しらぬ人、風雅におぼつかなし。
People who know nothing of the Tôkaidô have no understanding of fûga (poetic elegance).
-- Bashô. Cited in Sanzôshi 三冊紙 (Three notebooks).
2. 旅は風雅の花、風雅は過客の魂。
Travel is the flower of fûga; fûga is the spirit of the traveler.
-- (Bashô disciple) Kyoriku. From Infutaki 韻塞.
These phrases are discussed in a nice little book, Kazumi Yamashita's Bashô hyaku meigen 芭蕉百名言 (One hundred famous Bashô phrases), Kadokawa gakugei shuppan, 1996, 2010.
