When raising your vibration to reach finer states of consciousness it can be very easy to fall into a state of confusion. You need to anchor your presence. Grounding yourself means bringing your spirit into the present moment.
Your physical body is one part of your multidimensional self. It is no less important than your other aspects. If you are not grounded into the present moment you cannot manifest your self into your reality. Without the ability to manifest you cannot set out to do what you planned during this incarnation.
There is stigma surrounding the world of physicality that runs rampant throughout the New Age industry, insinuating that being physical is somehow 'less' than hanging out in the spirituall realms. This is simply not true.
As an awakening being you are setting out to bring your full spiritual presence into the moment. This is what awakening is. Without a strong foundation in the physical world you will have difficulty achieving this.
Enjoy your time here on this planet. The world of nature is beautiful and quite magical. So many people want to desperately 'get out of here' and they miss out on the Eden that is around them the whole time.
