Have you ever heard these teachings in the Soka Gakkai?

"In a scripture called the Nirvana Sutra, the Buddha says, “Rely on the Law and not upon persons.” Relying on the Law here means relying on the various sutras. NOT RELYING ON PERSONS means not relying on persons OTHER THAN THE BUDDHA, such as the bodhisattvas Universal Worthy and Manjushrī or the various Buddhist teachers I have enumerated earlier." - Repaying Debts of Gratitude

"To illustrate, suppose that a person is standing at the foot of a tall embankment and is unable to ascend. And suppose that there is someone on top of the embankment who lowers a rope and says, “If you take hold of this rope, I will pull you up to the top of the embankment.” If the person at the bottom begins to doubt that the other has the strength to pull him up, or wonders if the rope is not too weak and therefore refuses to put forth his hand and grasp it, then how is he ever to get to the top of the embankment? But if he follows the instructions, puts out his hand, and takes hold of the rope, then he can climb up.

If one doubts the strength of the Buddha when he says, “I am the only person who can rescue and protect others”; if one is suspicious of the rope held out by the Lotus Sutra when its teachings declare that one can “gain entrance through faith alone”; if one fails to chant the Mystic Law which guarantees that “such a person assuredly and without doubt [will attain the Buddha way],” then the Buddha’s power cannot reach one, and it will be impossible to scale the embankment of enlightenment.

Lack of faith is the basic failing that causes a person to fall into hell. Therefore, the sutra states, “If with regard to this sutra one should harbor doubt and fail to believe, one will fall at once into the evil paths.” - Questions and Answers on Embracing the Lotus Sutra
