The ultimate truth is tranquil and serene, with emptiness and stillness as its foundation. It illuminates all realms without deliberate thought, and responds without fixed form, clear and profound like still waters. However, because beings differ in their potential for awakening, transformative guidance cannot follow a single path. Thus, forms range from large to small, lifespans from long to short, teachings from subtle to coarse, and lands from pure to defiled. The methods for uplifting beings are countless, and the ways of awakening are not singular.
In the West, the Land of Ultimate Bliss (Sukhavati) is a pure realm inhabited solely by refined beings. That land was cultivated over countless ages, and the sages who inspired it were likewise long-enduring. The World-Honored One, Amitabha, riding on his past vows, manifested a pure land and established a long lifespan, enabling beings defiled by the five corruptions to cultivate superior karma. He allows aspirants of three grades to accumulate blessings over vast eons. With ten sincere recitations, their vows are fulfilled, and at death, they are reborn there. Those of nine grades establish their practice, and upon karmic retribution ending, they arrive immediately.
Speaking of that land: palaces of seven treasures, pools of gold, trees of jade—all reflect and enhance one another. Clothing and food arise naturally, meals offer a hundred flavors. Its inhabitants are solely the virtuous and the wise, cultivating together in harmony. Their bodies are purplish-gold, born spontaneously through transformation. They receive a body of emptiness and a form without limit. Their minds dwell in true reality, constantly proclaiming the Great Vehicle, discerning the true nature of phenomena, and experiencing boundless bliss.
The essence of this sutra can be understood in two aspects: First, it explains how the Dharma Treasury (Dharmākara) cultivated virtuous practices and achieved the reward of the Pure Land. Second, it encourages beings to cultivate good deeds so they may be reborn in that land.
The title says "spoken by the Buddha." Here, "Buddha" refers to Śākyamuni, the sovereign teacher of this world, who praises the long-term causes and conditions of Amitābha Buddha as well as the subtle and wonderful bliss of His land. Thus, it is called "spoken by the Buddha."
As for "Limitless Life": In the original Sanskrit text, He is called "Amitābha," which translates to "Limitless Life." Since His life span is extremely long, extending throughout countless eons, and since these eons are so vast that time itself becomes immeasurable, He is called "Limitless." "Life" refers to the unbroken continuity of form and mind. In terms of meaning, "life" and "lifespan" share the same essence but are different names. However, "lifespan" refers to a beginning and end, while "life" denotes an allotted period. Therefore, the term "Life" is used to indicate that He possesses an eternal duration that comes to an end.
The word "Sutra" indicates that even though the teachings of past and future Buddhas differ in their realization of the path, the words that convey the truth cannot be altered or changed. This clarifies the intent of the teaching.
When we examine the Buddha's teachings, they can be categorized into two types: the sequential teachings and the specific teachings. This particular sutra does not belong to the sequential teachings. How do we know this? Consider Shakyamuni's entire mission: his lifespan is described in four stages. Initially, it was said to be eighty years. Later, in the *Larger Prajñāpāramitā Sūtra* and the *Śūraṅgama Samādhi Sūtra*, it was said to be seven hundred *kalpas*. The *Lotus Sūtra* describes it as immeasurable, and the *Mahāparinirvāṇa Sūtra* emphasizes it as eternal.
Now, in explaining Amitābha Buddha, we learn that in the past, Dharmākara cultivated the causes and was born in the Western Land, attaining Buddhahood within an immeasurable lifespan. Because of this causal path, he achieved Buddhahood in one body. If we follow this reasoning, we should compare it to Shakyamuni's eighty-year lifespan in this world. How do we know? Just as a prince born in the palace, within eighty years, fully attains Buddhahood with a lifespan of only eighty years, similarly, Amitābha, within his immeasurable lifespan, fully attains omniscience and is also called the Buddha of Immeasurable Life. These two Buddhas are essentially the same, so their sutras should belong to the first period—thus making it an initial teaching.
However, the reason we say this sutra is not a sequential teaching is that it already discusses the causes of the One Vehicle and fully explains the deeds of Bodhi. Therefore, we know it is not an initial teaching, and thus it is a specific teaching. Yet, if it is said that its lifespan is the same as that of the *Lotus Sūtra* but not included in the *Lotus* teaching, it is because the *Lotus* is sequential, while this teaching is not; it arises to break attachments, so it is not absorbed into the *Lotus* teaching.
There are three interpretations of the Buddha’s lifespan in the *Lotus Sūtra*: First, some say it is also a reward-body Buddha, as in the previous teaching. Second, others say it is through supernatural power that a single moment is extended to countless *kalpas*. The sutra mentions that only after five hundred *yojanas* is the Buddha’s fruit revealed. Since this occurs within a transformed existence, Buddhahood is eternally complete, so one would enter nirvāṇa and yet prolong it, remaining in the world for an immeasurable lifespan. Third, others say it is a veiled teaching: the eternal is described as immeasurable, but within conditioned reward, there is this lifespan; however, the time and audience were not yet ready to fully understand the eternal, so it is spoken in a way that accommodates their hopes.
