It is stated in the Words and Phrases of the Lotus Sūtra, fascicle 9, “The seed of Buddhahood was planted by this Buddha-Bodhisattva at the beginning, and it was nurtured by this Buddha-Bodhisattva;” and in the Profound Meaning of the Lotus Sūtra, fascicle 6, “The Buddha appears in the actual world with form and figure to guide the people. How can those in whom He had planted the seed of Buddhahood not come to receive His guidance? As streams of many rivers all go into the ocean, people who have established a relationship with the Buddha can have the good fortune of encountering the Buddha in this life.”

As stated above, the Profound Meaning of the Lotus Sūtra, fascicle 6, preaches, “Properly speaking, all living beings will awaken aspiration for Buddhahood and proceed to it without falling back to a lower spiritual stage by following this Buddha.”
