I want to know about “At morning, First chant dwayam Sandhyavandanam [archarya thennian sloka] and then do sandhyavanam [praathah & mhaadhyanika sandhyavandanam] OR vice-versa. Which is correct?

WE ARE HAPPY FOR YOUR INTEREST IN MAINTAINING THE VEDIC PRACTICES.

INITIALLY AFTER BATH AND MARKING THE HEAD, ONE HAS TO CHANT GURU PARAMPARA AND 3 MANTHRAS, GIVEN BY OUR ACHARYAS. DURING THE COURSE ITSELF, DWAYAM WILL BE CHANTED. OTHERWISE, THERE IS NO TIME RESTRICTION TO DWAYAM. BUT RULES ARE HERE FOR SANDHYA VANDANAM. DWAYAMANTHRAM, IS NOTHING TO DO WITH OTHERS. SO ALSO SANDHYAVANDHANAM WITH DWAYAM TOO. AFTERNOON AND EVENING SANDHYAS SHOULD BE DONE AT THEIR OWN PLACES AND AT RECOMMENDED TIMES.
