I used to wonder the meaning of this part of Lotus Sutra:
"Thereupon he swallowed various perfumes, sandalwood, kunduruka, turushka, prikka, aloes, and liquidambar gum, and he also drank the fragrant oil of champaka and other kinds of flowers, doing this for a period of fully twelve hundred years. Anointing his body with the fragrant oil, he appeared before the Buddha Sun Moon Pure Bright Virtue, wrapped his body in heavenly jeweled robes, poured fragrant oil over his head and, calling on his transcendental powers, set fire to his body. The glow shown forth, illuminating worlds equal in number to the sands of eighty million Ganges. The Buddhas in these worlds simultaneously spoke out in praise, saying: 'Excellent, excellent, good man! This is true diligence. This is what is called a true Dharma offering to the Thus Come One. Though one may use flowers, incense, necklaces, incense for burning, powdered incensed, paste incense, heavenly silken banners and canopies, along with the incense of the sandalwood that grows by the southern seashore, presenting offerings of all such things as these, he can never match this! Though one may make donations of his realm and cities, his wife and children, he is no match for this! Good men, this is called the foremost donation of all. Among all donations, this is most highly prized, for one is offering the Dharma to the Thus Come One'"
- Chapter 23, Lotus Sutra
Is the sutra really asking for self-immolation?
Then I come across something my Shi fu said and understood it... My Master's disciple asked him why was he sometimes in Taiwan, sometimes in U.S, going overseas, in order to spread the dharma he did not rest at all, what is the reason? My master replied that there are two reasons:
(1) "Burning-Body" Body Offering to the Buddha (Ran2 Shen1 Gong4 Fo2) (2) Clear Karmic Hindrances
From this I think the "Self-Immolation" refers to wholeheartedly devoting/sacrificing oneself and one's body to the Triple Gems irregardless of anything, and that is the highest offering.
Sacrificing his own body for the practise of Bodhisattva way is also the highest offering.
