@PestiferMundi I take it from your thread that you have a hard time feeling energy.
This tutorial here deals with the concept energy manipulation via visualizing said energy in order to link a feeling to it:
Its not about opening chakras, but I think that especially the first exercise can be a helpful step by step guide to get a personal feeling about how energies feel like or look like (or even sound or taste like if you’re wired that way) to you, how they differ, how they interact, how they react. This can be applied to chakra meditation in the long run, in my experience. Every segment has a different kind of quality to it that can be perceived and played around with, once you’ve made yourself familiar with it.
To me personally I always found it super helpful when I could entertain a simple visual impression like a colour or a movement before the channels to “how does it feel like inside my body and where is it located?” opened. Over time this process has turned into instinct, like the way you’re operating a vehicle: you don’t think about it anymore while doing it. Remember the first awful time you’ve operated a bike or a car? Its a bit like that to me 
(for example my breathing exercise is to breathe into a visualized lemniscate instead of simply breathing in and out. following the trace of this symbol with my breathing pattern had to be visualized first before it started to flow naturally and without thinking about it)
