The teachings of Buddha may be difficult to understand, beyond ordinary conception. But as a practitioner, it is important to have faith in Buddha whose teachings are based on omniscience and full comprehension of the capacity of beings, instead of constantly following one’s own interpretations which are fickle, changeable, dependent on one’s current emotion, preferences, mental afflictions and flawed intelligence.
Quote from the Medicine Buddha Sutra :
At that time the World Honored One said to Ananda, “The merit and virtue of the World Honored One, Medicine Master Vaidurya Light Tathagata, which I have just extolled, is the extremely profound practice of all Buddhas. It is difficult to fathom and to comprehend. Do you believe it or not?”
Ananda said, “Greatly virtuous World Honored One, I have absolutely no doubts regarding the Sutras spoken by the Tathagata. Why? Because all Buddhas’ karmas of body, speech, and mind are pure. World Honored One, the sun and moon could fall, Wonderfully High, the king of mountains, could be toppled or shaken, but the words of the Buddhas never change.”
“World Honored One, there are sentient beings deficient in faith who hear about the extremely profound practices of all Buddhas and think to themselves, ‘How could one obtain such supreme merit and benefit merely by reciting the name of a single Buddha, Medicine Master Vaidurya Light Tathagata?’ Due to this lack of faith, they give rise to slander. During the long night, they lose great benefit and joy and fall into the evil destinies, where they wander ceaselessly.”
The Buddha told Ananda, “If these sentient beings hear the name of the World Honored One, Medicine Master Vaidurya Light Tathagata, and sincerely accept and uphold it without any doubts, they cannot possibly fall into the evil destinies.
Ananda, this is the extremely profound practice of all Buddhas which is difficult to believe and to understand! You should know that your ability to accept this comes from the awesome power of the Tathagata. Ananda, all Hearers, Solitarily Enlightened Ones, and the Bodhisattvas who have not yet ascended to the Grounds are incapable of believing and understanding this Dharma as it really is. Only the Bodhisattvas who are destined in one life to attain Buddhahood, are capable of understanding.
Ananda, it is difficult to obtain a human body. It is also difficult to have faith in and to revere the Triple Jewel. It is even more difficult to be able to hear the name of the World Honored One, Medicine Master Vaidurya Light Tathagata. Ananda, Medicine Master Vaidurya Light Tathagata possesses boundless Bodhisattva practices, limitless skillful expedients, and immeasurably vast, great vows. If I were to speak extensively of those for an eon or more, the eon would soon end, but that Buddha’s practices, vows, and skillful expedients have no end!”
