Plants planted in the house are not just for decoration, but they also deeply affect the energy, atmosphere and mental peace of the house. According to Vastu Shastra and Feng Shui, some plants attract positive energy, while there are some plants which can unknowingly increase stress, discord and negativity. Especially keeping thorny plants inside the house is considered inauspicious, because their thorns cause aggressive energy and obstacles. If you also have these plants in your house, then it would be better if you shift them outside to the garden or balcony.
