A bindi (Teeka) (from Sanskrit bindu,
meaning “a drop, small particle, dot”)
is a forehead decoration worn particularly in India.

Bindu (Sanskrit: बिंदु) is a Sanskrit term meaning “point” or “dot”. The feminine case ending is bindi which denotes a small ornamental, devotional, and often mystical dot that is cosmetically applied or affixed to the forehead in Hinduism. The symbol of the absolute is marked on the forehead at the position of the third eye, at the seat of the soul.

From Hindu Human Rights info For one to understand the true nature of the Teeka, one would have to understand the psychic/Ayurvedic perspective on anatomy. Specifically the system of chakras and auric sheaths. There are actually numerous symbols one might wear on the forehead for special occasions or to signify what sect of Hinduism the individual is from or follows.

Its main purpose is to remind the individual spiritual aspirant to look upon reality with the “mind’s eye” rather than just the physical eyes; which often only give half truths and delusions. In other words, the eyes only see that which is in the material, finite, outer world. The Teeka on the forehead reflects the notion of a spiritually infinite inner reality where the self and god are to be found.

Philosophy
In metaphysical terms, Bindu is considered the point where creation begins and may become the unity. It is also described as “the sacred symbol of the cosmos in its unmanifested state”. The bindu is the point around which the mandala is created and represents the manifestation of the universe. In Tantra, bindu symbolizes Lord Shiva, who is the source of creation. Bindu can also denote the silent point that is the source of all sacred sound. Most yantras and mandalas – both ritual designs, often circular or geometric – have the bindu at their center.

The bindu is often merged with seed, or sperm and ova. The Yoga Chudamani Upanishad states that the bindu exists as a duality, with a white bindu representing shukla (sperm) and a red bindu representing maharaj (menses). The white bindu resides in the bindu visarga and is related to Shiva and the Moon, while the red bindu resides in the muladhara chakra and is related to Shakti and the Sun. . .In yoga, it is the joining of these two parts that results in the ascension of the kundalini to the sahasrara. In Tantra, bindu or bindu visarga (“falling of the drop”) is a point at the back of the head and is represented by a crescent moon with a white drop. It represents the manifestation of creations, such as consciousness. The bindu visarga is said to be the source of bindu fluid containing a nectar (amrita) and a poison, stored in the lalana chakra and purified in the vishuddha chakra. When the vishuddha is inactive, the fluid is consumed and leads to physical degeneration. A hatha yoga practitioner can prolong his or her own life by controlling the flow of the fluid.
