Enchanted to meet you Detlef.
Yes, our choices can change the circumstances, but it is not always 'our choices' sometimes it is someone elses choice that changes our circumstance. So we really have no choice at times.
And if one asks for guidance in making choices, where does the guidance come from? Guides, angels or who?
Charmed*I'msure
When you follow your divine destiny your choices will manifest those people that you need in your life. Those that you do not need will fall away.
If they come back in your life it is only because you have manifested them by your awakening desire and spiritual understanding. Each one of us has his or her own guide angels and avatars depending on our current level of development and what suits are karmic background. It is our choices that have made the possibility of thinking that others have determined our destiny. However in reality we ourselves have made the choices that dictate the actions of those around us as well. It is by our own state of consciousness that creates our given situations. As we change our state of consciousness this becomes more evident. Blessings to all in this divine quest that has brought us at this point here and now. From this point we can make the choices that will lead to our further development and determine the environment and the people that come and leave in our lives.
