With Upasena
So I have heard. At one time the Buddha was staying near Rājagaha in the Bamboo Grove, the squirrels’ feeding ground. Then as Venerable Upasena son of Vaṅgantā was in private retreat this thought came to his mind: “I’m so fortunate, so very fortunate! My Teacher is the Blessed One, perfected, a fully awakened Buddha. Well explained is the teaching and training in which I have gone forth from the lay life to homelessness. My spiritual companions are ethical and of good character. I have fulfilled the precepts. My mind is unified and serene. I am a perfected one who has ended the defilements. I am of great might and power. My life has been good, and my death will be good.”
