In ancient Egypt the preparation for prayer was very thorough, Apparently, they had a separate room which was sprayed with scent - not incense, but a scent very much like almond blossoms - presumably from older varieties. Before prayers, they bathed and put on white raiments - the spiritual. All over the ancient world, people put a special place aside for that which dominated their lives. So there is nothing new in creating a spiritual haven and indeed, all over the world today people still do it.
Even the poorest Indian home has a space where images of Shiva and Krishna, or one of the other many faces of the deity, watch over the whole household; in front of which there is a small shrine for burning incense and saying prayers. A few Catholic homes are complete without a picture of Jesus or the Virgin Mary; in front of which eyes will be closed, hands put together, and prayers said; While all over Asia , countless images of Budda adorn quite, and fragrant, prayer corners. At any moment in time, literally millions of people all over the world will be in the midst of deep prayer in their own homes.
We create a spiritual haven to have a special place to focus on the spiritual, and to contact the higher realms. It's a place we will come back to time and time again, perhaps for different reasons. We may go there to seek peace, focus our minds, clear our thoughts, or just be. And it is there we can open our heart's to the love in the universe that waits to receive us. Aim to create a peaceful, restful place where the mind, body ad soul can concentrate on themselves for once, and be whole. It will be a place where you can draw the angelic beings close, and make your connection to the Universe and God.
Most of us do have the luxury of having a whole room to spare, but we can usually find a corner somewhere. That may be in the living room, bedroom, study or even the hall. Where is less important than what's in it, especially love. It is love in a house or place that makes it a sublime space to be in. The most exquisitely decorated palace is not beautiful if no love is generated there. The vibration of love, clear of negativity, carries prayer to its destination. It is the atmosphere of love that makes the haven spiritual.
If you never created a prayer space before, start by cleaning the area - and whole room - thoroughly. If it is a family room, do it when nobody is around. Clean everything, even inside wardrobes and cupboards, and have every ornament sparkle. While you do this, focus your mind on the divine, and imagine beautiful coloured lights, all the colours in white light, streaming into the room. If you like, play your favourite uplifting music. Not something that is 'beautiful' but just happens to be about unrequited love, and fills your eyes with tears and makes you sad. Play something that lifts up your spirits and fills you with optimism and joy.
