there is no requirement to be chaste or sinless to be reborn in the pure land
the sutras teach that only a desire to be born there and mindfulness of Amitabha's name are required to be reborn in his pure land
the 18th of Amitabha's 48 vows is such:
>設我得佛 十方衆生 至心信樂 欲生我國 乃至十念 若不生者 不取正覺 唯除五逆 誹謗正法
Supposing that I attain buddhahood, if sentient beings in any of the ten directions, with firm conviction and joy, should wish to be reborn in my land, even for the space of ten thoughts, but then are not born in my land, then I shall not take true enlightenment, only excluding the five parajika offenses, and slanderers of the true dharma
So the only sins capable of making you unfit for rebirth according to the sutras are slandering the dharma, and killing your parents or an arhat, shedding the blood of a buddha, or creating a schism in the sangha
the pure land is purposely created as a place open to all people almost unconditionally, which is perfectly suited to completing the bodhisattva path yourself, without distractions, where everything is conducive of singular mindfulness of the dharma
many teachers would say that the pure lands are not truly physical places but mental states that we create for ourselves, and that anywhere you are can be the pure land if you have the right intention
