نقلنا في مقال سابق عن الإيجابية وأهميتها وطرق اكتسابها، وإلحاقًا له، سننقل في مقال اليوم عن خطوة مهمة باتجاه الإيجابية، ألا وهي التخلص من الطاقة السلبية وتأثيرها في البيت والفرد والمجتمع والحياة بشكل عام. فما هي الطاقة السلبية وأسبابها في حياة الفرد؟ وكيف يمكن تفريغ الطاقة السلبية والتخلص منها؟
كل إنسان فينا يحمل في نفسه طاقة قد تكون إيجابيّة، وقد تكون سلبيَّة، وقد يمزج بين الطاقتين بحسب الموقف، فالطاقة الإيجابيَّة هي طاقة تحمل في طياتها الحب والعطاء والتفاؤل، أما الطاقة السلبية تزرع في قلب صاحبها، وتنعكس على سلوكه البغضاء والكراهية والسلبية والتشاؤم، وهناك طرق تكتسب خلالها الطاقة الإيجابيّة، وهناك نتائج لها على الفرد وعلى المجتمع. الطاقة...
