Honestly, I think Kundalini awakens, rather than you awakening it. There may be apparent triggering events (or not), and there are things that can facilitate it, but it seems to be rather like conception. It happens when and if it happens. You can prepare for it, do what you can to encourage it, etc., but it happens because it's meant to happen the way it happens, you know?

I know that's not very helpful, but that's just what I see now (after a couple of decades of working through the consequences and effects of an awakened Kundalini that completely and utterly destroyed me and my life and rebuilt same). It's okay to look for it, to look forward to it, but it will happen when and if it will happen.
