The well-known simile of the raft (_kullūpamaṁ_)[f68] which may seem somewhat unintelligible to some of the Buddhist critics who are used to an altogether different “intellectual landscape,” is a good illustration of the Buddhist teaching of non-attachment. The teaching, “Kullūpamaṁ vo bhikkhave ājānantehi dhammā pi vo pahātabbā, pageva adhammā,” (Like unto a raft all dharmas indeed must be abandoned, much more un-dharmas!), is really the most fundamental keynote running through the whole course of the history of Buddhist dogmatics. The philosophy of Prajñāpāramitā which is considered by some quite deviating from the spirit of primitive Buddhism is in no way behind in upholding this doctrine of non-attachment, for instance, as we see in the _Vajracchedikā Sūtra_. In fact, the theory of Śūnyatā as expounded in all the Prajñā-sūtras is no more than philosophising on the doctrine of non-attachment.[f69] The _Vajracchedikā_ has: “Tasmad iyaṁ thathāgatena sandhāya vāg bhāshi kolopamaṁ dharmaparyāyam ājānadbhir dharmā eva tā prahātavyāḥ prāgeva adharmā.” The simile itself runs as follows (Majjhima Nikāya, 22): “In the simile of a raft do I teach my doctrine to you, O monks, which is designed for escape, not for retention. Listen attentively and remember well what I am going to say. Suppose that a man coming upon a long journey finds in his way a great broad water, the hither side beset with fears and dangers, but the further side secure and free from fears, and no boat wherewith to cross the flood nor any bridge leading from this to the other shore. And suppose this man to say to himself: Verily this is a great and wide water, and the hither side is full of fears and dangers, but the further side secure and free from fears; and there is neither boat nor bridge to take me from this to that further shore. How if I gather some reeds and twigs and leaves and bind them together into a raft; and then, supported on that raft, and labouring with hands and feet, cross in safety to that other shore! Accordingly, O monks, suppose this man to gather together reeds and twigs and leaves and branches and bind them all together into a raft, and launching forth upon it and labouring with hands and feet, attain in safety the other shore. And now, the flood crossed, the further shore attained, suppose the man should say: Very serviceable indeed has this my raft been to me. Supported by this raft and working with hands and feet, I am safely crossed to this other shore; how now if I lift the raft up on my head or lay it upon my shoulder, and so proceed whithersoever I wish! What think ye, O monks? So doing, would this man be acting rightly as regards his raft? “Nay, verily, O Lord!
