The Anjali Mudra is also known as "Namaste" or "Namaskara." You probably recognize it from yoga and meditation. You simply bring your palms together near the heart chakra. The ends of the pinky fingers and thumbs must touch.

This hand symbol comes from the meditating Buddha. The hand rests pointing downward, appearing to touch the soil. Touching the earth represents enlightenment and spiritual awakening.

The Hopi Hand originated from the Native American tribes and looks like a hand telling you "hello" or "stop." There is a spiral in the palm, and it is believed to send out healing vibrations into the world around you. The spiraled palm represents the universe.

PVD coatings are applied in self-contained systems of different sizes. In the PVD process, a high-purity, solid coating material (metals such as titanium, chromium, and aluminum) is either evaporated by heat (arc evaporation) or by bombardment with ions (sputtering). At the same time, a reactive gas (e.g., nitrogen or carbon-containing gas) is added. The gas forms a compound with the metal vapor, which is then deposited on the tools or components as a thin, highly adherent coating. The process is carried out under high vacuum and, in most cases, at temperatures between 150 and 500 °C. A uniform coating thickness is obtained by rotating the parts at a constant speed around several axes.

There are too many hand symbols in the world to count, but there are several that are frequently used and have deep spiritual meaning. Here, we will list just 12 spiritual hand symbols, including nine that come from mediation practices called "mudras" to get into a certain state of mind. The last three appear in several modern religions and Native American culture.

Coating cutting and forming tools with PVD used in machines for manufacturing products significantly increase their service life and performance compared with uncoated tools and save on valuable raw materials, minimizing the environmental impact and helping to preserve natural resources.

American Indian culture associates the hand with the Great Spirit. They used hand gestures and sign language to overcome communication barriers between Indian nations.

Since then, it has been adapted by many religions around the world and the meanings vary. But when the hand is up, it protects the wearer against anything that would harm them, including the evil eye.

Your mudra hand represents these elements, with the thumb meaning fire, the index finger meaning air, middle fingers tied to space (the sky), the ring finger representing earth, and the pinky finger linked to water. Using each in the right balance can prevent illness and disease, and help with your emotional well-being.

That is why hand symbols are used in a number of spiritual practices. Those hand positions are intended to correlate with various parts of the human body.

In Buddhism, the hand is a symbol of protection, while Celtic people relate it to the rays of the sun. Chinese culture believes the hand is representative of longevity.

The Hand of Hamsa, also known as the Hand of Fatima, originated in Islam. As the story goes, Fatima, Mohammed’s daughter, found out her husband had married another woman and was so distraught, she stirred a pot with her bare hand. So, it came to represent the importance of being faithful.

To do this hand position, the right hand is cradled in the left hand, resting on your lap, and the palms face upward. Both thumbs are arched and touching to form a triangle at the base (sacral) chakra.

You may recall seeing this hand gesture on Thai and Burmese Buddha statues. The hand is upheld as if saying "hello" or "stop." It rids you of fear and protects you from negative energy. This hand position is intended to bring you peace, calm, and reassurance.

The coating properties, such as hardness, structure, chemical and temperature resistance, and adhesion, can be precisely controlled by the choice of metal and gas.

In Christianity, the hand of blessing represents The Father, The Son, and The Holy Spirit. Similarly, in Greek culture, a prominent hand symbol, the Hand of Sabazios, symbolizes the helping hand of God, protection, and healing.

Mudra means "seal" or "mark" in Sanskrit. The associated symbols have been used in Buddhist and Hindu culture forever as part of their ceremonial and religious practices. Mudras are secular so they aren’t attached to religion but are closely associated with spirituality, meditation, yoga, and breathing.

When the Hand of Hamsa is turned upside down, it represents abundance and prosperity. It is a sign that you welcome the good in life. You might find it worn on necklaces or on bracelets to usher in positivity.

Across cultures, hand symbolism is rich and varied. But most agree that what you do with your hands can have a great impact on mind, body, and spirit.

PVD coatings improve the performance and durability of precision components in almost any industrial and consumer good and extend the life of tools used in the metal and plastics processing industries.

Buddhi translates to "intellect" or "perception" in Sanskrit. This mudra sign is done by bringing the pinky finger and thumb together at the tips and pressing lightly to "seal" them. The middle, ring, and index fingers are pointed outward.

The key to the success of PVD coatings is finding the right coating solution for a specific application. For tools and components subjected to friction and wear, the first step is analysis of the entire tribological system — the parts and their required materials, the desired surface finish, the environment, and wear mechanism.

This symbol is done by touching the tip of your thumb with the index fingertip and holding the other three fingers straight, palm facing upward. It is one of the most popular mudras.

The Vayu is done by holding your hand up, facing forward, and pinning the tip of the index finger under the pad of the thumb, while the other three fingers remain erect and upright. This hand gesture regulates air in the body, relieving pain, supporting skin health, and reducing stress and anxiety.

PVD (Physical vapor deposition) is a technique for creating extremely hard and very thin coatings of a few thousandths of a millimeter.

The Apana Mudra uses both hands with the tips of the middle and ring fingers touching the thumb tip, while the index and small finger point upward. Its purpose is to strengthen your heart and improve the flow of your detoxification system, which includes your sweat, stool, and urine.

The Gyan helps with insight, concentration, knowledge-building, and memory. It can also reduce stress and improve focus.

The Buddhi Mudra enhances your spiritual connection, makes your thoughts flow freely, and takes you to a higher level of consciousness.

There are five categories of mudras: Yogic, customary, spiritual, curative, and religious. Based on the ancient Indian healing system, Ayurveda, mudra’s premise is that our bodies are made of five elements: Agni (fire), Vayu (air), Aakash (space), Pruthvi (earth), and Jal (water).

Precision components in vehicles, aircrafts, machines, medical technology, semiconductor technology, power generation and in many other devices are coated with PVD coatings to enable them to function more reliably, powerfully, and efficiently. The result is a reduction in friction and an increase in service life, which contributes to sustainability.

The Vitarka pose is just like the Gyan with the thumb touching the index fingertip ,while the other three fingers stand up. The only difference is that the palm is facing forward instead of upward.
