(Extracted from Sutra on the Buddha of Eternal life or Larger
SUKHAVATI-VYUHA)
And now, O Ananda, stand up, facing westward, and having taken a
handful of flowers, fall down. This is the quarter where that
Bhagavat Amitabha, the Tathagata, holy and fully enlightened,
dwells, remains, supports himself, and teaches the Dharma, whose
spotless and pure name, famed in every quarter of the whole world
with its ten quarters, the blessed Buddhas, equal to the grains of
the sand of the river Ganges, speaking and answering again and
again without stopping, extol, praise, and eulogize.'
After this, the blessed Ananda said this to the Bhagavat : 'I wish,
O Bhagavat, to see that Amitabha, Amitaprabha, Amitayus, the
Tathagata, holy and fully enlightened, and those noble-minded
Bodhisattvas, who are possessed of a stock of merit amassed under
many hundred thousand nayutas of kotis of Buddhas.'
At that moment this speech was spoken by the blessed Ananda, and
immediately that Amitabha, the Tathagata, holy and fully
enlightened, let such a ray of light go out of the palm of his own
hand, that even the most distant Buddha country was shining with
the great splendor. And again at that time, whatever black
mountains, or jewel-mountains, or Merus, great Merus, Mukilindas,
great Mukilindas, Chakravadas, great Chakravadas, or erections, or
pillars, trees, woods, gardens, palaces, belonging to the gods and
men, exist everywhere in hundred thousand kotis of Buddha
countries; all these were pervaded and overcome by the light of
that Tathagata.
Most of all know that Venerable Ananda has still not attained
Arahanthood yet, maybe 1st or 2nd stage of sainthood. (Those who
want to be certain, please check other sutras which speaks of his
spiritual progress.)
So what am I trying to say? If Venerable Ananda has attained
non-attachment, he does not really need to ask to see Amitabha
Buddha and the Pureland with his own eyes. Just believe in
Sakayamuni Buddha will do. Of course, one can say that he had asked
for the sake of all future sentient beings (in order to quell their
doubts and suspicions about the existence of Amitabha Buddha and
Pureland), which is not wrong at all and is supported by verses in
the first chapter of the scripture.
However, notice the Buddha's reaction to his request. His request
was granted just like that.
I mean a real-life Buddha is just in front of him in the form of
Sakayamuni Buddha, why does he need to know how Amitabha Buddha
looks like? All Buddhas have the same 32 characteristics. The only
difference is the range with which the light of each Buddha shines
upon the different universes and realms.
Most Buddhas' light can at least reach more than 3 big thousand
worlds, but Amitabha Buddha's light can reach infinite worlds in
all ten directions. Hence the name of the Buddha of Infinite light,
Unobstructable light and so on.
Anyway, the Buddha did not say something like "Amitabha Buddha
looks just like me, so don't worry. For all Buddhas tell only the
truth". Something like that is usually enough to make most believe
in the existence of Amitabha Buddha and his Pureland.
If I were to be one of the disciples of Sakayamuni Buddha, and I
can already see a real life Buddha sitting in front of me, I don't
think I will have any doubts at all about the existence of
Pureland. Why do you doubt when you can already see with your own
eyes how a real-life Buddha in human form looks like? I don't think
I will be that bo liao. 
So actually seeing is still believing for those who have not yet
achieved non-attachment.
