釋淨土群疑論 7.33

7.33

釋曰：諸大乘經說此三昧其文極眾，如《華嚴經》數處皆說念佛三昧，其文極廣，故《涅槃經》、《觀佛三昧海》、《賢護》、《般舟三昧》、《觀經》、《鼓音聲王》、《大集月藏分》、《地藏十輪經》、《占察經》、《文殊般若》、《花首經》、《大智度論》等說。如《花首經》名一相三昧，《文殊般若》名一行三昧，《觀佛三昧海經》名觀佛三昧，《賢護經》名思惟諸佛現前三昧。《花首經》言「如是菩薩於如來相及法界相，常如是觀、如是行。不離是緣，是時佛像即現在前而為說法。」《文殊般若》言「隨佛方所，端身正向，不取相貌，係心一佛專稱名字，念念無休息。即是念中，能見過去現在未來三世諸佛。何以故？念一佛功德無量無邊，即與無量諸佛功德無二，是名一行三昧。」《涅槃經》言「若人但能至心常修念佛三昧者，十方諸佛恒見此人，如現目前。」《觀佛三昧海經》及《賢護經》最廣明是念佛三昧，不可具說。勸諸行者披尋聖教，自當得知也。

Explanation: The passages across the Mahāyāna sūtras that explain this samādhi are extremely numerous. For example, the Avataṃsaka Sūtra in several places explains the buddhānusmṛti-samādhi in very extensive passages. It is also expounded in the Nirvāṇa Sūtra, the Guanfo sanmei hai jing, the Bhadrapāla Sūtra, the Pratyutpanna-samādhi Sūtra, the Guan jing, the Sūtra of the King of Drum-Sound, the Candragarbha section of the Mahāsaṃnipāta Sūtra, the Daśacakra Kṣitigarbha Sūtra, the Divination Sūtra, the Mañjuśrī Prajñāpāramitā, the Kusumasāñcaya Sūtra, the Mahāprajñāpāramitopadeśa, and so forth. For example, the Kusumasāñcaya Sūtra names it 'single-mark samādhi' (ekalakṣaṇa-samādhi); the Mañjuśrī Prajñāpāramitā names it 'single-practice samādhi' (ekavyūha-samādhi); the Guanfo sanmei hai jing names it 'buddha-contemplation samādhi'; the Bhadrapāla Sūtra names it 'samādhi of meditating on the Buddhas standing before oneself' (pratyutpannabuddhasaṃmukhāvasthitasamādhi). The Kusumasāñcaya Sūtra states: 'Such a bodhisattva constantly contemplates and practices in this manner regarding the marks of the Tathāgata and the marks of the dharmadhātu. Without departing from these conditions, at that time the form of the Buddha appears right before them and preaches the Dharma for them.' The Mañjuśrī Prajñāpāramitā states: 'In accordance with the Buddha's direction, sit upright facing directly toward it, not grasping at marks, bind the mind to one Buddha and exclusively recite his name, thought-moment after thought-moment without cessation. Right within that mindfulness, one can see the Buddhas of the three times—past, present, and future. Why? The merit of mindfulness of one Buddha is immeasurable and boundless, and is no different from the merit of immeasurable Buddhas; this is called the single-practice samādhi.' The Nirvāṇa Sūtra states: 'If a person is merely able to constantly cultivate the buddhānusmṛti-samādhi with sincere mind, the Buddhas of the ten directions will constantly see this person as though appearing right before their eyes.' The Guanfo sanmei hai jing and the Bhadrapāla Sūtra explain this buddhānusmṛti-samādhi most extensively; it cannot be detailed completely. I urge all practitioners to unroll and examine the sacred teachings, and they will naturally come to know this.
