Nikola Tesla, among other scientists, firmly believed that one’s intention and thought interacted with the environment in an unseen way. Discoveries in quantum physics have since demonstrated this long after Nikola Tesla. This lecture from Bob Proctor is a classic explanation of the law of attraction.
Also, be sure to study successful people like Andrew Carnegie, Napoleon Hill, and Earl Nightingale whom also utilized these principles.
The law of attraction ties into quantum entanglement theory which was scientifically demonstrated in 2022 for which the Nobel Prize was awarded. Reference that summary at the bottom on the Education Resources page, here.
