Please take a look at this book. It reports many times pieces of the Rig Veda. For example on page 25.
May the three-seated (tri-vandhura) and mentally-governed (manasa-yukta) come – spreading over the five abodes (Rig Veda VII.69.2)
Or on page 95:
'In the wild ecstasy of divine immortality, I destroyed all the ninety-nine cities of Shambara; And utterly the hundredth abode, when helping the servant of the gods in the Atithgva lineage' (Rig Veda. IV.26.3)
I tried to find the original texts in the Rig Veda. But in those verses there is completely different text. And sometimes there is no reference at all.
I am expecially interested in this one:
According to the Vedas, there are Seven Chakras in each 'layer', of which consists of Three Worlds. But, there are 33 'Layers' of these Chakras, of which correspond to the Thirty Three Gods of the Vedic Philosophy (Rig Veda. II.6.9).
This one does not seem to be a citation. Anyway there is not such as II.6.9 - the last verse is 8.

Can anyone help to find (Rig Veda. II.6.9) and to explain why on page 95 based on that verse(s) he states that there are ninety-nine chakras?
