Sandhyā-vandanam
Dr. K. Aravinda Rao
A Vedic Meditation on the Suprme Reality

This book deals with the Sandhya-vandanam (SV hereafter) according to the Yajur-Veda tradition, thus intended for the people of that sect. There are some minor variations in the SV meant for the persons belonging to the Rig-Veda, Sama-Veda and Atharva-Veda sects but the underlying philosophy is same for all the versions of the SV. There may be regional variations of minor nature even for the SV of Yajur-Veda, which do not matter much.
