This Sandhyavandanam Performing vintage post card is not in my collection. One person from England giving me permission for using his Indian vintage post cards images in my Heritage of India blog. Sir thank you very much for your encouragement.
In India it is a common practice to performing Sandhyavandanam by Brahmins particularly Hindu Priests in the morning. Some people performing Sandhyavandanam by 3 times also. The three times are Morning (Prataha Sandhyavandanam), Afternoon (Madhyahna Sandhyavandanam) and Evening (Sayam Sandhyavandanam). During the Sandhyavandanam time people worship Gayatri Maa and performing the procedure of Sandhyavandanam by reciting atleast 108 times of Gayatri Mantra.
