I have found this Dhanwantari Gayatri Mantra:
Om Vasudevaya Vidmahe Vaidhyarajaya Dhimahi Tanno Dhanvantri Prachodayat
This Mantra can be found on Internet, but also I have this book Исцеляющие мантры в Аюрведе (Russian Edition), where this Mantra is a bit different:
Om Vasudevaya Vidmahe Djagad-rakshaya Dhimahi Tanno Dhanvantri Prachodayat
Sorry for maybe wrong spelling as in this book Mantra is written using Cyrillic.
What is the difference between
Vaidhyarajaya Dhimahi and
Djagad-rakshaya Dhimahi? Thank you!
