Lotus Sūtra（《法華經》） is an important Mahāyāna sūtra. It influenced Chinese Buddhism widely. It is a fundamental sūtra of T’ien-t’ai Buddhism. “Dharma Lotus Samādhi” (法華三昧) was the key way of the practices of Hue-si (慧思) and Zhi-yi (智顗) who were the most important patriarchs of T’ien-t’ai sect. I classify sixty practice ways of Lotus Sūtra to be five classes and explain them. The main practice way of Lotus Sūtra is to practise and preach Lotus Sūtra itself. It mentioned “Contemplation of Emptiness” (空觀), but didn’t explain “Dharma Lotus Samādhi” directly, and didn’t mention “Contemplation of Illusory Phenomenon” (假觀), “Contemplation of Middle Way” (中道觀), “Threefold Contemplation in One Single Mind” (一心三觀) neither. Hue-si established “Dharma Lotus Samādhi” of T’ien-t’ai sect by himself, without consulting “Si-wei-lve-yao-fa”（《思惟略要法》）. I analyze and induce that Hue-si took five kinds of practise ways of Lotus Sūtra in this paper. I present and explain the ways and states of “Dharma Lotus Samādhi” made by Hue-si. I also make a comparison table of seven biographies of Hue-si. Furthermore, I interpret Huesi’s theory of “Dharma Lotus Samādhi” according to “Fahua-jinganlexingy”（《法華經安樂行義》）. According to Hue-si’s thought, the practice way of “Lotus Sūtra” can accomplish the Buddha way directly and quickly. But it can be taken by anyone who believes and accepts Lotus Sūtra, even the new learners who can practise by themselves. I deduce that the cases shown in Lotus Sūtra that “Everyone Likes to See Bodhisattva”( 一切眾生憙見菩薩) and “Miao-zhuang-yan king”(妙莊嚴王) got Samādhis in just a lifetime which are the basic thougat of Hue-si that the practice way of Lotus Sūtra can accomplish the Buddha way quickly and Zhi-yi declared that one could reach the stage of “First Settling”(初住位) by “Contemplation of Perfect-teaching”(圓教觀) in a lifetime. But it is Hue-si who declared that getting the Samādhis also meant to get Buddha’s miraculous abilities, being predicted to become a Buddha, getting all kinds of wisdom and Buddha-eyes. Hue-si thought there were two kinds of practice ways “Having Form Practice”(有相行) and “Without Form Practice”(無相行) in Lotus Sūtra. The former is to read Lotus Sūtra and can get “Six Roots of Senses being Purified”(六根清淨) and three kinds of dhāraṇī. I explained it’s detailed procedures according to Guan-Pu-Xian-Bodhisattva Sūtra (觀普賢經). Hue-si thought this practice way could acquire “Five Eyes”, “Three Kinds of Wisdom” and all Buddha dharmas. I think that according to the case of “Miao-zhuang-yan king”, and “Having Form Practice” one can arrive the final achievement. Hue-si was an example of getting “Dharma Lotus Samādhi” by reading Lotus Sūtra during three lifetimes. “Without Form Practice” is “Four Anlexing” (四安樂行). Its major way is based on the thought of “tathāgata-garbha”(如來藏) and one can contemplate directly on “buddha nature” to accomplish the Buddha way quickly. But what it takes is the way of “Contemplation of Emptiness” instead of “T
