As I talked about in a recent post, the main core idea of the venerable Tendai (天台) sect in Japanese Buddhism, including its parent Tiantai sect in China, is that the Lotus Sutra is the most important text in the Buddhist canon, a kind of capstone (lit. “complete teaching”, engyō 円教) for the rest of Buddhist literature up to that point. Because the Lotus Sutra is pretty long (equivalent to a modern book), I tried to summarize its teachings here.
Anyhow, Tendai/Tiantai focuses on how to put the Lotus Sutra into practice. For Japanese Tendai in particular, this is encapsulated in a phrase called shishū yūgō (四宗融合) meaning “Four Integrated Practices”. According to my book, these are listed as follows:
- Meditation1
- Esoteric Practices (mantras, dharani, mandala, etc)
- Precepts
- Pure Land2
This a lot. It helps to think of Tendai as a big umbrella or parasol with a bunch of people standing under it.

Different people under the umbrella represent different Buddhist followers, with different practices and inclinations, but the umbrella itself represents the concept of upāya (“expedient means”) or hōben (方便) in Japanese. This is one the main themes of the Lotus Sutra, and expresses that all Buddhist teachings and practices lead toward the same end goal, and thus whatever works for a person at that time is perfectly fine for that person.
This is encapsulated in the 25th chapter of the Lotus Sutra, the so-called Kannon Sutra, because the Bodhisattva Kannon (a.k.a. Guan-Yin, Avalokiteshvara, Chenrezig, Quan Âm, etc) according to this chapter takes on whatever form is most beneficial for that person and teaches the Dharma to them. Thus, Kannon can appear as a man, woman, monk, rich person, etc. It’s also why statues of Kannon often depict them as having 1,000 arms, each holding a different object. Similarly, many of the early Buddhist monks who were Tendai followers practiced it differently from one another. On the one hand, you have monks like Eisai, who focused on meditation and precepts (and would later found the first Rinzai Zen temples), you also had monks like Genshin who focused a lot more on Pure Land practices, as well as esoteric experts such as Ennin.
Tendai as a sect in Japan was almost universal in the 9th through 12th centuries, but for a variety of historical (often self-inflicted) reasons, it has diminished in size and influence. Yet when you visit historical temples in Japan such as Asakusa Temple in Tokyo, Kiyomizudera Temple in Kyoto, and Sanjusangendo in Kyoto, these are all Tendai temples. Further, its influence lives on in newer sects that we know well: Zen, Pure Land, Nichiren and such, which all inherited practices and concepts even if they apply them in differing ways.
But while Tendai as an organized sect is somewhat diminished,3 its teachings of “umbrella” or “universal” Buddhism continue to live on. Rather than insisting there’s only one way to practice Buddhism, it gives a large, spacious framework for people to figure out their own path and use the vast toolkit available to work it out, all under the Lotus Sutra concept of expedient means. Use what works for you, and do not be afraid to adapt, change, or expand your practice as you go.

1 Tendai/Tiantai has the same meditation tradition as Zen, but tends to call it shikan (止観) not zazen (座禅) meditation. The founder, Zhi-yi, in China wrote multiples treatises, the Mohe Zhiguan, that provides a comprehensive manual about meditation. I have a copy of the The Essentials for Practicing Calming-and-Insight & Dhyana Meditation, but have only read parts of it. It is a nice training manual for those interested, but it is a little dense since the intended audience was the monastic community.
2 In the time of Zhi-yi, the founder of Tiantai, Pure Land Buddhism was approach more as a meditation tradition than a separate set of practices that what we see today. By the time it came to Japan, this had changed somewhat, and we see through the writings of Genshin that there were a variety of approaches both devotional and meditation-focused.
3 According to my book, as of 2015, the number of registered followers in Japan was around 1.5 million give or take. This makes it the second smallest of the major sects in Japan, and one-eighth the size of Jodo Shinshu-sect Buddhism. Only Rinzai Zen is smaller (1.1 million).
