Yes, in this context I was referring to the practice of asanas, meditation & breathwork. Since this text wasn't specifically about yoga, I didn't feel inclined to go further into details about the particularities of the word (although "an analogy for life" kind of eludes to the fact that it's much more than a physical practice).
I really like this excerpt:
"Yoga is a particularly polyvalent Sanskrit word, which, in ordinary usage, may signify joining or attaching, a means or method or way, profit or wealth, a trick or deceit, an undertaking or business, mixing, putting together or ordering, suitability, diligence or magic.” ― “Roots of Yoga” by James Mallinson and Mark Singleton
or this one...
“Be steadfast in the performance of your duty, abandoning attachment to success and failure. Such equanimity is called Yoga.” ― Bhagavad Gita
