This quote by Nikola Tesla speaks to the healing and nourishing power of nature. When Tesla refers to the beauty and scent of roses as a medicine, he is suggesting that the aesthetic and sensory pleasures derived from nature have a therapeutic effect on our minds and bodies. This could be interpreted as a nod towards aromatherapy, a holistic healing treatment that uses natural plant extracts to promote health and well-being. The scent of roses, for example, is often associated with relaxation and stress relief.

The second part of the quote, “the sun rays as a food,” suggests that sunlight, like food, is essential for our survival and well-being. This is a scientific fact as sunlight is a key source of Vitamin D, which is crucial for bone health, immune system function, and overall mental health.

Applying this quote in today’s world could mean incorporating more nature into our daily lives for its therapeutic benefits. This could involve spending more time outdoors, cultivating a garden, or even bringing more plants into our homes and workplaces. It could also mean recognizing the importance of sunlight in our lives and making sure we get enough of it, for example, by taking short breaks to go outside during the day or arranging our workspaces to get more natural light.

In terms of personal development, this quote could inspire us to cultivate a deeper appreciation for nature and to recognize its role in our physical and mental health. It could also encourage us to seek out more natural remedies and therapies, and to consider the ways in which our environments affect our well-being.
