To me the term sadhana simply means worship or discipline, in just about any form, be it simply offering light, incense, sweets; a round of japa or meditation; and/or prayers of praise, blessings, forgiveness.
I know there are very abbreviated versions, and very long versions. Even Hindu pujas (without meditation or japa) can take anywhere from 2-20 minutes at home and up to 2 hours at temple. Because I say prayers to a multiplicity of deities, both Hindu and Buddhist (Tara, Chenrezig, Manjushri and Medicine Buddha; I'm not empowered), do several japas of 108 repetitions (Avalokiteshvara, Tara, Vishnu, sometimes Shiva), and meditation, I found that my "sadhana" typically takes about an hour. I have a short version in which I offer light, incense, sweets, I say some mantras and a few generic prayers, and maybe a little meditation if I don't feel I can give it "my all". That can take 10-20 mins.
So, I am just wondering how long people generally spend in sadhana.
