The Daishonin writes: “Suppose a lion has a hundred cubs. When the lion king sees its cubs attacked by other beasts or birds of prey, he roars; the hundred cubs will then feel emboldened, and the heads of those other beasts and birds of prey will be split in seven pieces” (WND, 949).
The practice of the hundred cubs, who represent the disciples, is to gain courage from the roar of the lion king, the mentor, and defeat other beasts and birds of prey that attack them.
In other words, if the disciples only rely on the mentor to battle and defeat devilish forces without taking on the struggle themselves and emerging victorious, they cannot possibly carry on the mentor’s spirit.

None of us believe from the start that we possess great power and ability. But when we gain courage from the mentor, the strength to take action and fight wells forth in our lives. We already possess that strength and ability within us. When we embrace the Mystic Law that is the lion king, that power and ability naturally well forth.

From the perspective of those who are the Buddha’s disciples, people who just revere the Buddha from afar as mere bystanders do not qualify as genuine disciples.
Unless we wage a great struggle for the happiness of all people with the same dedication as the mentor—just as the Buddha and the Bodhisattvas of the Earth have struggled together as one since the distant past—we cannot call ourselves the lion’s cubs. Worse, if we are lion cubs whose actions incur the ridicule of “foxes,” then we do not qualify as successors of the lion king.
We only carry on the legacy of the Lotus Sutra, the scripture of the oneness of mentor and disciple, when we firmly make the heart of a lion king our own and struggle as one with the mentor.

To assert that the Buddha exists apart from human beings and that ordinary people are only ever destined to be guided by the Buddha is not genuine Buddhism. The Lotus Sutra teaches that all people are Buddhas, and that Shakyamuni seeks to enable all to attain the same lofty state of life as he.
