Sanskrit terms and correlates

Aspart of my continued research into Rta, I am looking for the
origins and correlates of other terms most commonly associated with
Rta.

The following are some words I would greatly appreciate any possible
assistance with. I have given brief translations, most come from H.D.
Griswold's "The Religion of the RigVeda"

1) daksa = will
2) dharman = statute
3) dhaman = decree
4) kratu = will
5) satya = true
6) vrata = ordinance - related to the Latin 'verbum' and
English 'word' --- thus originating from the PIE *were3



My thanks as always,
Aydan
