Great moments are born from great opportunity.

From my childhood I had been intended for the clergy. This prospect hung like a dark cloud on my mind.

The idea came like a flash of lightning, and in an instant, the entire concept was revealed.

The Buddhist expresses it in one way, the Christian in another, but both say the same: We are all one.

It’s not the love you make. It’s the love you give.

Every action creates a force of energy that returns to us in like kind.

I myself eschew all stimulants. I also practically abstain from meat.

The earth is but one country, and mankind its citizens.

The progressive development of man is vitally dependent on invention. It is the most important product of his creative brain.

You may live to see man-made horrors beyond your comprehension.

No free energy device will ever be allowed to reach the market.

Archimedes was my ideal. I admired the works of artists, but to my mind, they were only shadows and semblances. The inventor, I thought, gives to the world creations which are palpable, which live and work.

To find out the truth, you must not be afraid to be wrong.

Marconi is a good fellow. Let him continue. He is using seventeen of my patents.

Throughout the infinite, the forces are in a perfect balance, and hence the energy of a single thought may determine the motion of a universe.

Our entire biological system, the brain, and the Earth itself, work on the same frequencies.

As in nature, all is ebb and tide, all is wave motion, so it seems that in all branches of industry, alternating currents – electric wave motion – will have the sway.

The mind is sharper and keener in seclusion and uninterrupted solitude.

I am even grateful to Einstein and others because through their erroneous theories they lead mankind away from that dangerous path I followed.

So astounding are the facts in this connection, that it would seem as though the Creator, himself had electrically designed this planet…

Peace can only come as a natural consequence of universal enlightenment.

The feeling is constantly growing on me that I had been the first to hear the greeting of one planet to another.

A great scientist is a great teacher.

Life is and will ever remain an equation incapable of solution, but it contains certain known factors.

The gift of mental power comes from God, Divine Being, and if we concentrate our minds on that truth, we become in tune with this great power. My Mother had taught me to seek all truth in the Bible.

Electric power is everywhere present in unlimited quantities and can drive the world’s machinery without the need of coal, oil, gas, or any other of the common fuels.

The year 2100 will see eugenics universally established. In past ages, the law governing the survival of the fittest roughly weeded out the less desirable strains. Then man’s new sense of pity began to interfere with the ruthless workings of nature. As a result, we continue to keep alive and to breed the unfit.

I am not a inventor; I am a discoverer.

Let the future tell the truth, and evaluate each one according to his work and accomplishments. The present is theirs; the future, for which I have really worked, is mine

Of all the frictional resistances, the one that most retards human movement is ignorance.

Every living being is an engine geared to the wheelwork of the universe. Though seemingly affected only by its immediate surrounding, the sphere of external influence extends to infinite distance.

There is no conflict between the ideal of religion and the ideal of science, but science is opposed to theological dogmas because science is founded on fact. To me, the universe is simply a great machine which never came into being and never will end. The human being is no exception to the natural order. Man, like the universe, is a machine.

We crave for new sensations but soon become indifferent to them. The wonders of yesterday are today common occurrences.

All that was great in the past was ridiculed, condemned, combated, suppressed — only to emerge all the more powerfully, all the more triumphantly from the struggle.

If you only knew the magnificence of the 3, 6 and 9, then you would have the key to the universe.

Anti-social behavior is a trait of intelligence in a world full of conformists.

I do not think there is any thrill that can go through the human heart like that felt by the inventor as he sees some creation of the brain unfolding to success… such emotions make a man forget food, sleep, friends, love, everything.

The individual is the product of the environment.

Of all things, I liked books best.

Alpha waves in the human brain are between 6 and 8 hertz. The wave frequency of the human cavity resonates between 6 and 8 hertz. All biological systems operate in the same frequency range. The human brain’s alpha waves function in this range and the electrical resonance of the earth is between 6 and 8 hertz. Thus, our entire biological system – the brain and the earth itself – work on the same frequencies. If we can control that resonate system electronically, we can directly control the entire mental system of humankind.

My brain is only a receiver, in the Universe there is a core from which we obtain knowledge, strength and inspiration. I have not penetrated into the secrets of this core, but I know that it exists.

Our virtues and our failings are inseparable, like force and matter. When they separate, man is no more.

What one man calls God, another calls the laws of physics.

I could only achieve success in my life through self-discipline, and I applied it until my wish and my will became one.

Be alone, that is the secret of invention; be alone, that is when ideas are born.

If your hate could be turned into electricity, it would light up the whole world.

Modern science says: ‘The sun is the past, the earth is the present, the moon is the future.’ From an incandescent mass we have originated, and into a frozen mass we shall turn. Merciless is the law of nature, and rapidly and irresistibly we are drawn to our doom.

The present is theirs; the future, for which I really worked, is mine.

The scientists of today think deeply instead of clearly. One must be sane to think clearly, but one can think deeply and be quite insane.

I don’t care that they stole my idea . . I care that they don’t have any of their own.

If you want to find the secrets of the universe, think in terms of energy, frequency and vibration.

It is paradoxical, yet true, to say, that the more we know, the more ignorant we become in the absolute sense, for it is only through enlightenment that we become conscious of our limitations. Precisely one of the most gratifying results of intellectual evolution is the continuous opening up of new and greater prospects.
