To my knowledge, the Gaudiya tradition does not require
their adherents to perform Veda adhyayanam (recitation and
study of the Veda in the traditional manner), and therefore
Gaudiyas generally do not do so. Gaudiya Vaishnavas, including
the ISKCON movement, do not recite the Veda, do sandhyAvandana,
or other daily duties incumbent on Vaidikas and practiced
by the orthodox in other denominations.
Please correct me if I am wrong.
If what I say is correct, and Gaudiyas do not do
Veda adhyayanam, sandhyAvanda, etc., it cannot be said
that they study the Veda or that they are Vaidikas in
the same sense as other traditional scholars in India.
And if they do not study and recite the Veda along
with all its accompanying disciplines such as grammer,
pronounciation, etc., they are not qualified to comment
This is the view held by the scholarly Vaidika community.
