Sama Veda Sandhyavandanam

Over the years, I realized that being a Sama Vedi Iyer was one of the most challenging things from the point of view of online resources for rituals. Ok, Sandhyavandanam is something a guy is supposed to have learnt from his Aacharyaal since the day the Upanayanam was performed, but somehow things didn't work out for me.
Googling "Sama Veda Sandhyavandanam" didn't really help much and I really had to dig deep for a proper link that contained exactly what I was looking for. I'm basically reproducing the content from Shri P.R.Ramachander's page here, since this page isn't available among the first few results, and I'm hoping my blog-post is easier to locate.

PS: This post strictly details the procedure for Sama Vedi Iyers. Non-{Sama Vedi Iyers} have ample resources elsewhere, so do kindly excuse. Also, I'm not keen on this turning out to be a discussion-point for casteism/Brahminism, so if you want to oppose/criticise such rituals, etc, sorry, this is not the place.

Part-I - Argya Pradhanam

1. Aachamanam: आचमनः
Take small quantities of water (just sufficient to soak one grain of black gram) three times in the right hand and take it with the following manthra:
Om Achyuthaya Namah, Om Ananthaya Namah, Om Govindaya Namah


Then
Touch with thumb both cheeks saying Kesava - Narayana
Touch with ring finger both eyes saying Madhava - Govinda
Touch with the first finger both sides of nose saying Vishno - Madhusoodana
Touch with little finger both ears saying Trivikrama - Vamana
Touch with the middle finger both shoulders saying Sreedhara - Hrishikesa
Touch with all fingers the belly button saying Padmanabha
Touch with all fingers the head saying Damodara.

2. Ganapathi Dhyanam:
Recite the following manthra slowly hitting the forehead with both fists together:

3. Pranayamam:

The inhaling is called Puraka, the retaining Kumbhaka and the exhaling Rechaka. The proportion of time of these three viz. Puraka, Kumbhaka and Rechaka should be in the ratio 1: 3: 2.
Puraka, Kumbhaka and Rechaka together, make one Pranayama. From Om Bhuh upto Dhiyo yo nab prachodayat would be Puraka. From Omapo Jyoti-rasomritam Brahma Bhurbhuvassuvarom upto Om Bhuh, Om Bhuvah will be one Kumbhaka.The third turn from Om Bhuh upto the end will be Rechaka.
