Hi dear @anon65589122 ,
Glad you like to include them in daily life.
I learnt them from some old books on yoga like Gherand Samhita and Hatha Yoga Pradipika. Also verified in some YT videos (there are many versions of the postures online, so need to be cautious). I stick to original version mentioned in the books.
Here are some excerpts from books(Hatha Yoga Pradipika)
About bandhaa and Mudras-
About Jalandhar bhandha-
About Uddiyan bhandha-
About Mool bhandha-
About Mahabandha-
When all the three bandha are performed simultaneously, it’s called Mahabandha.
Three bandhas in short-
About Mahamudra-
In case you are comfortable with sanskrit and hindi (Gherand Samhita)
जालंधर बंध
मूलबंध
उडडीयान बंध
महाबंध
महामुद्रा
Sambhavi Mahamudra does include Bandhas, so three bandhas are part of it. I was not aware of it. Shambhavi Mudra and Shambhavi Mahamudra are different though.
Wish you all the best

PS. Corrected the reply about Shambhavi Mahamudra.
