妙法蓮華經玄義 4.133

4.133

四、煗法位者，以別、總念處觀故，能發似解十六諦觀，得佛法氣分。譬如鑽火煙起，亦如春陽煖發，以慧鑽境，發相似解，解即喻煖。又如春夏積集華草，自有煖生，以四諦慧，集眾善法，善法熏積，慧解得起，故名煖也。即是內凡初位，佛弟子有、外道則無，是名煗法位。

4. The stage of the heat dharma: through the contemplations of specific and general mindfulness, one can produce a simulated understanding of the contemplation of the sixteen truths and obtain a portion of the Buddha-Dharma. It is like the smoke rising when drilling for fire, or like warmth arising in the spring sun; drilling into the object with wisdom produces a simulated understanding, and understanding is compared to heat. Again, it is like gathering flowers and grasses in spring and summer, which naturally generates heat; gathering various wholesome dharmas with the wisdom of the four truths, as wholesome dharmas accumulate through fumigation, the wisdom-understanding is able to arise; hence it is called heat. This is the first stage of the internal ordinary person; disciples of the Buddha possess it, while non-Buddhists do not; this is called the stage of the heat dharma.
