Achamanam being the starting point of Sandhyavandanam, this must be a preparation of the Sadhak for further kriyas. The Gayatri chanting part is the central part of the Sandhyavandanam.Īchamanam removes the ill effects of today’s hectic lifestyle such as Constipation, Stress, fatigue etc.The mental effects are subtle. Hence such periods were chosen for Sandhyavandanam to derive maximum concentration. They are in a continued state of agitation during the daytime but, tend to follow a uniform path during the sandhya periods. The nadis ida and pingala are the paths of flow of Prana or life force. Otherwise, he warns, one’s Brahmanathva itself is wasted. Sri Abhinava Theertha swamigal says whatever be the grade, it is always best to do it regularly. Hence this is classified in the Nithya karma, which has to be done daily, lifelong. Sunrise and sunset are the reason for doing Sandhya vandanam. Nithya karma is one which is ‘niyata nimitta’ meaning ‘ that which is done which is shastra bound’. Naimithika karma is one which is not shastra bound and not niyamic, i.e., a necessary duty, such as taking bath after an eclipse. Even if kamya karmas are not done, there is no sin. Kamya karma is one which is done with a desire to achieve, like a yagya for long life etc. There are three types of Karmas- Nithya, Naimithika, and Kamya karmas. One who does not perform Nitya Karma Anushtanam like Sandhyavandanam is always impure and Whatever other rites he may perform, he will not obtain the fruits thereof.
