'Brahmans' are the one of the earliest category of Hindu scriptures. 'Satpatha Brahman' is the most famous among them. 'Panchvinsh Brahman' belongs this category. 'Vedic Index" vol.I&II.by Macdonell often quotes from this book. Some of the references quoted from this book by Mcdonell are quite perturbing to me particularly about a king who murdered his priest because he insisted to worship Indra.
I want to verify this from the original text of 'Panchvinsh Brahman'. May anyone help me by suggesting it's availability online or a book form that can be purchased online or even the publisher where this book may be available.
