Shakyamuni
Buddha said:
“For
what reason, Śāriputra, do you think that Buddha is called Amitābha? Śāriputra,
the Buddha’s light shines boundlessly and without hindrance over all the worlds
of the ten directions. It is for this reason that He is called Amitābha. Again,
Śāriputra, the lives of the Buddha and the people of His land last for
innumerable, unlimited, and incalculable kalpas. It is for this reason
that the Buddha is called Amitāyus.
Śāriputra,
ten kalpas have passed since Amitāyus attained Enlightenment. Moreover,
Śāriputra, He has an immeasurable and unlimited number of śrāvaka disciples,
all of them arhats, whose number cannot be reckoned by any means. His assembly
of Bodhisattvas
is
similarly vast. Śāriputra, that Buddha land is filled with such splendid adornments.”
As Shakyamuni confirms, Amida (Amitabha/Amitayus) is now a
Buddha because “ten kalpas have passed” since He attained Enlightenment
(Buddhahood). This is why in the Larger Sutra or the Smaller Sutra
and Contemplation Sutra, He no longer calls Him Bodhisattva Dharmakara which
was His name when He was in the causal stage, but “Amitayus”, which means
Infinite Life, or “Amitabha” - “Infinite Light”. These two aspects,
“Infinite Life” (Amitayus) and “Infinite Light” (Amitabha) are merged in
Japanese Buddhism into the word “Amida”,
which means the Buddha of Infinite Life and Infinite Light. His Infinite
Life is the effect of the 13th Vow He made when He was Dharmakara
Bodhisattva, while the Infinite Light is the effect of His 12th Vow.
So, we cannot separate Amitayus (Infinite/unlimited Life) from Amitabha
(Infinite/Boundless Light) because these are the two aspects of the same Buddha
as Shakyamuni explained in section 4 of this sutra.
