Nava Sutta
Nava Sutta：Once a novice，returning from his alms round，entered his cell and sat down in silence and at ease，not helping the monks with the robe making．
This was reported to the Buddha，who sent for the monk．
The Buddha discovered his abilities，and told the monks to leave him alone as he was one who could win，without toil，the four jhānas （S．ii．277）．

Nāvā Sutta：1．Nāvā Suttaalso called Damma Sutta．Itwas preached in reference to Sāriputta’s habit when he was on tour of worshipping the direction in which his teacher，Assaji，lived．Others noticed this and said it was a relic of his old brahmanic habit of worshipping the different quarters．But the Buddha said there was no need of Sāriputta to do that，for even the devas themselves worshipped him．In the sutta the wise man is compared to a ship （nāvā） which takes many others across．SN．vs．316 23； SNA．i．325ff．
