to a senior monk, Subhuti. Its major themes are anatman (not-self), the emptiness of all phenomena (though the term 'śūnyatā' itself does not appear in the text), the liberation of all beings without attachment and the importance of spreading and teaching the Diamond Sūtra itself. In his commentary on the Diamond Sūtra, Hsing Yun describes the four main points from the sūtra as giving without attachment to self, liberating beings without notions of self and other, living without attachment, and cultivating without attainment. According to Shigenori Nagatomo, the major goal of the Diamond Sūtra is: "an existential project aiming at achieving and embodying a non-discriminatory basis for knowledge" or "the emancipation from the fundamental ignorance of not knowing how to experience reality as it is". In the sūtra, the Buddha has finished his daily walk to Sravasti with the monks to gather offerings of food, and he sits down to rest. Elder Subhūti comes forth and asks the Buddha: "How, Lord, should one who has set out on the bodhisattva path take his stand, how should he proceed, how should he control the mind?" What follows is a dialogue regarding the nature of the "perfection of insight" (Prajñāpāramitā) and the nature of ultimate reality (which is illusory and empty). The Buddha begins by answering Subhuti by stating that he will bring all living beings to final nirvana, but that after this "no living being whatsoever has been brought to extinction". This is because a bodhisattva does not see beings through reified concepts such as "person", "soul" or "self", but sees them through the lens of perfect understanding, as empty of inherent, unchanging self. The Buddha continues his exposition with similar statements which use negation to point out the emptiness of phenomena, merit, the Dharma (Buddha's teaching), the stages of enlightenment and the Buddha himself. Japanese Buddhologist Hajime Nakamura calls this negation the "logic of not" (na prthak). Further examples of the Diamond Sūtra via negativa include statements such as: "As far as 'all dharmas' are concerned, Subhuti, all of them are dharma-less. That is why they are called 'all dharmas'." "Those so-called 'streams of thought', Subhuti, have been preached by the Tathagata as streamless. That is why they are called 'streams of thought'." All beings', Subhuti, have been preached by the Tathagata as beingless. That is why they are called 'all beings'." The Buddha is generally thought to be trying
