If you didn’t prostrate or said what they had said, you didn’t commit shirk but surely you were sinful for not leaving the place immediately, once you discovered this.

I joined a course 3 days before named YES+ but i was unaware about their doings. They told us that they are going to increase our focus and concentration towards our studies by simply doing a breathing exercise. Ist 2 days were normal but on the 3rd day they meditate us by playing some hindu slokas and also we did sajda’s towards 4 directions, but i was chanting only AllAH’S name.Did i do shirk ??
