Question: Some say that Buddhahood is only attainable through Tantra practices. If so, and since most Pure Land practitioners do not practise Tantra, can they attain Buddhahood in Amituofo’s [Amitabha Buddha] Pure Land?
Answer: Everyone can manifest all the levels of enlightenment in Amituofo’s Pure Land – to even become the greatest Bodhisattvas on the brink of Buddhahood. Even though Buddhahood is in spirit realisable there, personal Buddhahood is always manifested outside the hosting Buddha’s Pure Land out of compassion to benefit more beings. Amituofo’s Pure Land’s guaranteed high efficiency of training future Buddhas is stated clearly in the Amitabha Sutra by Sakyamuni Buddha –
‘Among them [all beings in Amituofo’s Pure Land, who are all spiritually non-retrogressible], many are in the Stage Of One Life To Replacement [of preceding Buddhas in other world systems; Eka-jati-prati-baddha]. Their number is extremely great, and cannot be known by counting, and can only with immeasurable and boundless asamkhyeya [incalculable] kalpas be spoken of.’
All forms of Dharma practices can be fully mastered in Amituofo’s Pure Land. Even if Tantra practices, which some say can lead to enlightenment in one lifetime are practised these days in our world in this Dharma-ending age, not many can realise enlightenment, unless they are already very well-practised in previous lives. This is why our era is called the Dharma-ending age. It is also why Sakyamuni Buddha clearly taught in the Immeasurable Life Sutra that the practice of reaching Pure Land is the most feasible practice in this age.
Having reached Amituofo’s Pure Land, one is bound for the swiftest Buddhahood. Staying here, there is not only no guarantee for Buddhahood, there is the risk of repeatedly facing the problem of three lifetimes: http://thedailyenlightenment.com/2010/08/are-you-recycling-yourself-every-three-lifetimes. Even some relatively ‘junior’ tulkus (recognised reborn masters) who did not reach Pure Land or enlightenment in the last life can experience backsliding upon return to this world: http://thedailyenlightenment.com/2015/05/full-review-what-if-you-are-a-tulku-recognised-reborn-master
This is why even great masters such as Guru Rinpoche (Padmasambhava: founder of Buddhism in Tibet), Lama Tsongkhapa (founder of the Gelug school of Tibetan Buddhism and author of the Lam-rim Chen-mo), Nagarjuna (founder of the Madhyamaka school) and many others highly recommend practice to be born in Amituofo’s Pure Land: http://thedailyenlightenment.com/2015/10/guru-rinpoche-lama-tsongkhapass-exhortation-to-reach-pure-land
