First, for you to ask a question about the Lotus Sutra is a rare source of good fortune.
In this age of the Latter Day of the Law, those who ask about the meaning of even one phrase or verse of the Lotus Sutra are
much fewer than those who can hurl great Mount Sumeru to another land like a stone, or those who can kick the entire galaxy
away like a ball. They are even fewer than those who can embrace and teach countless other sutras, thereby enabling the priests
and laymen who listen to them to obtain the six mystic powers. Equally rare is a priest who can explain the meaning of the
Lotus Sutra and clearly answer questions concerning it. The Hoto chapter in the fourth volume of the Lotus Sutra sets forth
the important principle of six difficult and nine easy acts. Your asking a question about the Lotus Sutra is among the six
difficult acts. This is a sure indication that if you embrace the Lotus Sutra, you will certainly attain Buddhahood. Since
the Lotus Sutra defines our life as the Buddha's life, our mind as the Buddha's wisdom and our actions as the Buddha's behavior,
all who embrace and believe in even a single phrase or verse of this sutra will be endowed with these three properties. Nam-myoho-renge-kyo
is only one phrase, but it contains the essence of the entire sutra. You asked whether one can attain Buddhahood only by chanting
Nam-myoho-renge-kyo, and this is the most important question of all. It is the heart of the entire sutra and the substance
of its eight volumes.
