Hi Raj!
Any time you don't understand something, ask for clarification. The other than conscious mind communicates via symbolism that the conscious mind may not clearly comprehend at first. The next time you do the exercise build into your intention a request that any symbolism be clarified and distilled so you know what it represents and what to do with it.
It's amazing what wisdom lies within us once we request additional clarification.
All the best!
