The passage
Diamond Sūtra section 6, in paraphrase (Kumārajīva's Chinese translation, 402 CE): "Subhūti, these bodhisattvas' and mahāsattvas' wisdom has no grasping at marks of self, other, sentient beings, lifespan. They do not grasp at the mark of dharma, nor the mark of non-dharma. "Why? If they grasp at the mark of dharma, they would grasp at self, other, sentient beings, lifespan. If they grasp at the mark of non-dharma, they would also grasp at self, other, sentient beings, lifespan. "Therefore one should not grasp at dharma, nor grasp at non-dharma. For this reason, the Tathāgata often says: 'Monks, my teaching is like a raft. Even the dharma should be abandoned, much less the non-dharma.'"
Why the raft, not a more elevated metaphor
The Buddha could have compared his teaching to many things: a treasure, a light, a seed, a king, a medicine. Each metaphor has been used at different times in the tradition. The raft is specifically chosen because it is unambiguously instrumental. A raft exists only to get you across a river. Once across, its continued presence is a liability — carrying it on your back up the hill is absurd, not respectful. Other metaphors preserve some sense in which the thing is valuable in itself. A treasure is worth keeping; a light is worth preserving; a seed grows into something you want. The raft's value is purely functional. When the function is done, the value is done. The Buddha, in the Diamond Sūtra and earlier in the Alagaddūpama Sutta (MN 22), chose the unambiguously instrumental metaphor to prevent exactly the kind of confusion that other metaphors invite. The teaching is useful, then empty, then unnecessary. Clinging to it past the point of use is the mistake the metaphor names.
What "abandoning even correct dharma" means operationally
This is the part most commonly misunderstood. "Abandon the dharma" does NOT mean: - Stop practicing - Disrespect the teachings - Reject Buddhism - Move to a "higher" non-Buddhist teaching Each of these is another form of clinging — clinging to the rejection, clinging to a higher teaching, clinging to the idea of going beyond. What it means operationally: when a specific Buddhist teaching has done its work in you — produced its specific shift, integrated its specific insight — the conscious holding of the teaching dissolves. You don't "reject" the Heart Sūtra once it has landed; you stop having the experience of carrying it as a load-bearing structure. The sūtra's insight is now simply how you see; the text becomes one helpful document among many, not the axis around which your practice revolves. Same for every specific teaching. The Four Noble Truths, once fully integrated, don't need to be consciously consulted; suffering-and-its-end is simply how you experience the world. The eightfold path, once walked, is no longer a checklist; ethical conduct, concentration, and wisdom operate without the list being internally recited. This is the sense in which the raft is abandoned. Not thrown away in anger. Not treasured as memorial. Simply no longer carried as luggage because the function it performed has been completed.
The key danger: premature abandonment
The Diamond Sūtra teaching is abused when taken as permission to abandon teachings that haven't yet done their work. "The raft should be abandoned — so I don't need to follow the precepts." This is not the sūtra's teaching; this is the acquiring-frame's strategy for avoiding the precepts. The precepts haven't done their work yet; abandoning them means not crossing the river, not reaching the far shore where abandonment becomes natural. "The raft should be abandoned — so I don't need to read sūtras." Same error. Sūtras are the raft; abandoning them before they have carried you across is not wisdom but incomplete practice wearing wisdom's clothing. The practical marker: genuine abandonment feels like no-longer-needing; premature abandonment feels like avoidance. If you can sit with a specific teaching (precept, sūtra, technique) and ask honestly whether you have completed its work, the answer is usually clear. Most practitioners most of the time have not finished with the raft they are currently on.
Sequenced rafts
The Buddhist path can be read as a sequence of rafts, each abandoned at its completion: - Ethical precepts — carried early, integrated, become natural behavior - Concentration practices — sustained attention develops, eventually operates without deliberate effort - Insight into impermanence, unsatisfactoriness, non-self — initially intellectual, becomes direct seeing - Specific doctrinal frameworks (Four Noble Truths, dependent origination) — initially studied, become operational reality - Advanced teachings (śūnyatā, Buddha-nature, bodhisattva ideal) — initially acquired, eventually dissolve as separate items At any given point, the practitioner is on several rafts simultaneously. Some are still carrying them across; some are near-abandoned; some are still being carried loyally past the point of use. The Diamond Sūtra's teaching is that awareness of the raft-structure of teaching is itself part of the path. Without it, practitioners tend to stockpile teachings, treating each as a permanent acquisition, and the practice accretes rather than progresses. With it, the practitioner recognizes when a teaching's work is done and releases it, clearing space for the next teaching to do its specific work.
