Nichiren stressed the idea that the Buddha's pure land is [[Immanence|immanent]] in this present Saha world (''shaba soku jakkōdo'') and that all beings have the innate potential to attain [[Buddhahood]] in this very body (''sokushin jōbutsu''), though this can only be achieved by relying on the ''Lotus Sutra''. Nichiren was influenced by earlier ideas taught by [[Kūkai]] and [[Saicho]], who had taught the possibility of becoming a Buddha in this life and the belief all beings are "originally enlightened" (''[[Original enlightenment|hongaku]]'').<ref>{{Cite book |last=Shaner |first=David Edward |url=https://books.google.com/books?id=haVhiTONzOYC&q=sokushin+jobutsu&pg=PA75 |title=The Bodymind Experience in Japanese Buddhism: A Phenomenological Study of Kukai and Dogen |date=1985 |publisher=SUNY Press |isbn=978-0-88706-061-8 |pages=75–79 |access-date=3 October 2020 |archive-url=https://web.archive.org/web/20220602012407/https://books.google.com/books?id=haVhiTONzOYC&q=sokushin+jobutsu&pg=PA75 |archive-date=2 June 2022 |url-status=live}}</ref><ref>{{Cite book |last=Groner |first=Paul |title=The Lotus Sutra in Japanese Culture |date=1989 |publisher=University of Hawaii Press |isbn=978-0-8248-1198-3 |editor-last1=Tanabe |editor-first1=George J. |pages=56–57 |chapter=The Lotus Sutra and Saicho's Interpretation of the Realization of Buddhahood with This Very Body |access-date=31 October 2018 |editor-last2=Tanabe |editor-first2=Willa J. |chapter-url=https://books.google.com/books?id=O03rvTi0vwAC&pg=PA53 |archive-url=https://web.archive.org/web/20220704214116/https://books.google.com/books?id=O03rvTi0vwAC&pg=PA53 |archive-date=4 July 2022 |url-status=live}}</ref><ref name=":0" />

In the [[Tendai]] school, these theories were also closely related to [[Chih-i|Zhiyi's]] theory of the "mutual inclusion of the ten Dharma-realms" (''jikkai gogu'' 十界互具), also called [[Zhiyi#The Sublime mutual inclusion|Three Thousand Realms in a Single Thought]] (''ichinen sanzen'' 一念三千), as well as on [[Zhanran]]'s view of the all-pervasive character of [[buddha-nature]].<ref>{{Cite book |last=Fowler |first=Merv |title=The Wiley Blackwell Handbook of Humanism |date=2015 |publisher=John Wiley & Sons |others=Andrew Copson and A.C.

Nichiren saw ''ichinen sanzen'' as pointing to the potential for Buddhahood in all beings (ri no ichinen sanzen 理の一念三千) and to the actualization of Buddhahood itself (ji no ichinen sanzen 事の一念三千), which encompasses and illuminates all other realms. He associated these with the "trace" teaching of the first half of the ''Lotus Sutra'' and with the "origin" teaching of the latter half of the sutra respectively.<ref name=":0" /> He also saw ichinen sanzen as the ultimate truth and the heart of the ''Lotus Sutra'', writing that "only the [[Tiantai]] ichinen sanzen is the path of attaining Buddhahood".<ref>Stone 2003, p. 263.</ref> However, he also saw his own teaching of ichinen sanzen as different and as going beyond that which was taught by Zhiyi. This is because Nichiren held that his teaching of the "true ichinen sanzen" was based on the latter half of the ''Lotus Sutra'' (the origin teaching), instead of on chapter 2. For Nichiren this is "the doctrine of original cause (hon’in) and original effect (honga). The nine realms are inherent in the beginningless Buddha realm; the Buddha realm inheres in the beginningless nine realms." This teaching "demolishes" all views of gradual training.<ref>Stone 2003, pp. 264-263</ref>
