The adaptation process of a Sirian star seed is very complex and necessary in order to fulfil its missions on planet Earth, to learn the necessary lives' lessons on present incarnation, to be connected with Sirian star family, to access energies and pieces of information from star beings.The book describes in an originally and synthetically manner:- Preparatory activities at: physical, psychical, social and energetically levels.- Criteria necessary for individualizing preparatory activities.- Examples of practices at: physical, psychical, social and energetically levels.The book is written in a pragmatic manner giving precise indications to the readers. Each chapter has its own bibliography for further and more complex studies.I recommend this book to all Sirian star seeds that are in the quest of their spiritual essence.
