Our own research revealed Anahata as the fourth primary chakra, according to the Hindu, Yogic, Shakta, and Tantric Buddhist traditions. In Sanskrit, anahata translates to English as unhurt, unstruck and unbeaten. Anahata Nad refers to the Vedic concept of unstruck sound, the sound of the celestial realm. Anahata usually is associated with a calm serene sound that is void of violence. The Anahata chakra is positioned in the central channel in the spine at the heart region, with its kshetram or superficial activation site actually in the heart region between the two breasts.
It is represented by a smoke-grey lotus flower, with 12 petals. Inside of it is a smoke-colored region that is made from the intersection of two triangles, creating a shatkona. The shatkona is a symbol used in Hindu Yantra that represents the union of both the masculine and feminine form. More specifically it is supposed to represent Purusha (the supreme being), and Prakriti (mother nature, or causal matter). Often this is represented as Shiva - Shakti. The deity of this region is Vayu, who is smoke colored, four-armed, holding a kusha and riding upon an antelope, the animal of this chakra.
The seed syllable is the mantra 'Yam', dark-grey in color. Within the bindu or dot above the syllable resides the deity Isha (Lord in an all pervading form). Isha is either shining white or blue in color, has either 1 or 5 faces with 3 eyes on each face; has 2, 4 or 10 arms, is clad in a tiger skin, holds a trident and a drum and/or is making gestures of granting boons and dispelling fear. His shakti is Kakini, who is shining yellow or rose in color. She has a number of variations, having either 1, 3 or 6 faces, 2 or 4 arms, and holding a variety of implements, occasionally a sword, shield, skull and trident. She is seated on a red lotus.
The twelve petals are vermilion in color, and upon them are inscribed the syllables kam, kham, gam, gham, ngam, cham, chham, jam, jham, nyam, tam and tham in Sanskrit. They match the vrittis of lust, fraud, indecision, repentance, hope, anxiety, longing, impartiality, arrogance, incompetence, discrimination and defiance.
Anahata is considered the seat of the Jivatman, and Para Shakti. In the Upanishads, this is described as being like a tiny flame that resided inside the heart. Anahata is so called because it is in this place that sages hear that sound (Anahata – Shabda) which comes without the striking of any two things together.” It is associated with the element of air, the sense of touch, and with actions of the hands.
Anahata is associated with the ability to make decisions outside of the realm of karma. In Manipura and below, man is bound by the laws of karma, and the fate he has in store for him. In Anahata, one is making decisions, 'following your heart', based upon one's higher self, and not from the unfulfilled emotions and desires of lower nature. As such, it is known as the heart chakra. It is also associated with love and compassion, charity to others, and forms of psychic healing.
Meditation on this chakra is said to bring about the following siddhis, or occult powers; he becomes a lord of speech; he is dearer than the dearest to women; his senses are completely under control, and he can enter at will into another's body.
