Spiritual growth, real Heaven and Hell
From my perspective, as we grow spiritually, expand our consciousness, and raise our vibration, we leave one dimension and enter another one. We might drop our vibration at times and visit the old dimension, but we must be aware to immediately take action to raise our vibration, through meditation, prayer, or anything that brings us joy, otherwise we risk getting stuck there again for a while. I believe that is what the messengers of God were trying to tell us when they talked about Heaven and Hell. I believe we put ourselves in either state, depending on our actions, emotions and outlook.
When I am experiencing something that makes me joyful, I say thank you, and imagine, what if I have died and this is what Heaven is. This perspective usually keeps me on a high vibration, and I manifest things that I want easily and more loving, peaceful and joyful experiences come my way. I have also experienced the opposite, and I do not recommend it! 🙂
So always be mindful of the frequency of your vibration!
