faith can be a last minute thingy where they meet a good advisor of Pureland during their deathbed, and they accept and believe. they will still be reborn in PL. i have seen nuns liberating a female ghost (possessing on a lady) into PL. the ghost was also a first time believer, right on the spot, she accepted Amitabha.
check Contemplation Sutra.
Starting from the lowest level of the middle grade to the middle level of the lowest grade. i am sure it's not the the lowest level of the lowest grade. http://www12.canvas.ne.jp/horai/contemplation-sutra.htm
6) the lowest level of the middle grade
 "Those who attain birth on the lowest level of the middle grade are good men and women who are dutiful to and care for their parents and do benevolent deeds for others. When such a person is about to die, he may meet a good teacher, who fully explains to him the bliss of the land of Amitayus and the Forty-eight Great Vows of the Bhiksu Dharmakara. Having heard this, he dies and in the short time it takes a strong man to bend and straighten his arm, he attains birth in the Western Land of Utmost Bliss. Seven days after his birth there, he meets Avalokiteshvara and Mahasthamaprapta, rejoices at hearing the Dharma from them and so reaches the Stage of a Stream-Winner. After one smaller kalpa, he becomes an Arhat. Such a person is called one who attains birth on the lowest level of the middle grade. These three together are known as the contemplation of the middle grade of aspirants and the fifteenth contemplation. To practice in this way is called the correct contemplation, and to practice otherwise is incorrect."
7) the highest level of the lowest grade
 The Buddha said to Ananda and Vaidehi, "Those who attain birth on the highest level of the lowest grade are the sentient beings who commit various evil acts but do not slander the Mahayana sutras of greater scope. When a foolish person such as this, who has committed much evil but feels no remorse, is about to die, he may meet a good teacher, who praises the titles of the twelve divisions of the Mahayana scriptures. By hearing these sutra-titles, he is released from the burden of evil karma which he has accumulated during a thousand kalpas. Furthermore, this wise teacher advises him to join his palms and call, 'Homage to Amitayus Buddha' [Na-mo-o-mi-t'o-fo].' Calling the name of the Buddha extinguishes the evil karma that the dying person has committed during fifty kotis of kalpas of Samsara.
"The Buddha then sends his transformed body and those of Avalokiteshvara and Mahasthamaprapta to the aspirant; they praise him, saying, 'Well done, man of good deeds! By calling the Name of the Buddha your evil karma has been extinguished, and so we have come to welcome you.' When these words are uttered, the aspirant sees a flood of light from that transformed Buddha fill his room. Having seen this, he rejoices and dies. Seated on a jewelled lotus-flower, he follows the transformed Buddha and is born on a jewelled pond.
In seven weeks the lotus-bud opens and Avalokiteshvara, the Bodhisattva of Great Compassion, and Mahasthamaprapta appear before him, releasing great floods of light, and explain to him the extremely profound teachings of the twelve divisions of the scriptures. Having heard these, the aspirant accepts them in faith, and awakens aspiration for the highest Enlightenment. After ten smaller kalpas, he acquires clear understanding of the one hundred dharmas and enters the First Stage of Bodhisattvahood. Such a person is called one who attains birth on the highest level of the lowest grade. Thus he is born by hearing the Name of the Buddha, the Dharma and the Sangha -- that is, the Three Treasures."
8) the middle level of the lowest grade
 The Buddha said to Ananda and Vaidehi, "Those who attain birth on the middle level of the lowest grade are the sentient beings who violate the five precepts, the eight precepts or the complete precepts of a monk or a nun. A foolish person such as these steals from the Sangha or takes the personal belongings of monks, or preaches the Dharma with impure motives but feels no remorse. Thus he [346a] defiles himself by evil karma, and because of this he will fall into hell.
"When he is about to die and the flames of hell suddenly close in on him, he may meet a good teacher, who compassionately explains to him the ten supernal powers of Amitayus, fully describing the majestic power of the light of that Buddha, his virtues in the observance of the precepts, meditation, wisdom, emancipation and knowledge of emancipation. When he has heard this, the evil karma which he has committed during eighty kotis of kalpas of Samsara are extinguished; thus, the fierce flames of hell turn into cool and refreshing breezes, wafting heavenly flowers. On each flower is a transformed Buddha accompanied by bodhisattvas welcoming him.
"In an instant, he attains birth within a lotus-bud on a seven-jewelled pond. After six kalpas the lotus-bud opens, and then Avalokiteshvara and Mahasthamaprapta comfort him with their noble voices and teach him profound Mahayana sutras. Upon hearing these, he immediately awakens aspiration for the highest Enlightenment. Such a person is called one who attains birth on the middle level of the lowest grade."
so, also, it is not necessary people reborn in the outskirt of PL are still in lotus-bud.
Asaik, seeing Amitabha at deathbed and predicting one's departure are very very good sign of a person reborning in PL.
much better than having (flower) shariras in cremation. having soft body are quite good too.
let's contemplate further....whether mara can display as Amitabha to trick the dying, who is a beginner in Amitabha believe. i think it's much difficult for mara to do so for a first time believer, as they do not have much confusion. it's more for long time practitioner who practice multiple Buddhas and got themselve confuse with whom to follow.
