In ancient India, kitchens were considered sacred spaces, and some wealthy Indians had built-in indoor tropical rainforests. These rainforests were designed to create a serene and spiritual environment for cooking and dining. The Indians believed that the lush greenery and flowing water in the rainforest would bring blessings and positive energy to their meals. The kitchen would be filled with the fragrance of exotic flowers and the sound of waterfalls, creating a tranquil and meditative atmosphere. The rainforest also provided a sustainable source of fresh ingredients, as the Indians grew a variety of fruits, vegetables, and herbs in their indoor gardens.
