5.8.10

Ye hi keci, ānanda, cetiyacārikaṃ āhiṇḍantā pasannacittā kālaṃ karissanti, sabbe te kāyassa bhedā paraṃ maraṇā sugatiṃ saggaṃ lokaṃ upapajjissantī”ti.

Anyone who passes away while on pilgrimage to these shrines will, when their body breaks up, after death, be reborn in a good place, a heavenly realm.”
