Sahasrara (Sanskrit) is the seventh primary chakra according to Hindu tradition although many don't consider it to be a chakra like the others; it is said to transcend them all.

Sahasrara is positioned above the head or at the top of it and it is said to have 1000 petals which are arranged in 20 layers each of them with 50 petals although by most accounts yogis say the sahasrara in fact is infinite.

Bindu is a Sanskrit term meaning "point" or "dot". The feminine case ending is Bindi which denotes a small ornamental, devotional and/or mystical dot that is cosmetically applied or affixed to the forehead in Hinduism.

Ajna (Sanskrit meaning 'command') is the sixth primary chakra according to Hindu tradition.

The Ajna chakra is positioned at the eyebrow region and has two white petals, said to represent the psychic channels, Ida and Pingala, which meet here with the central Sushumna nadi (channel) before rising to the crown chakra, Sahasrara. These petals also represent the manifest and unmanifest mind, as well as the pineal and pituitary glands. 'Ham' is the letter of the left petal, and 'ksham' is the letter of the right petal, representing Shiva and Shakti, respectively. "Pranava Om", the supreme sound, is the bij, or seed mantra of this chakra.

Vishuddha (Sanskrit) also known as Vishuddhi, is the fifth primary chakra according to Hindu tradition.

Vishuddha is positioned at the neck region and it has sixteen petals corresponding to the Sanskrit vowels. Vishuddha is associated with the faculty of higher discrimination, between choosing what is right and wrong, and it is associated with creativity and self-expression. It is known as the 'poison and nectar' centre, closely related to the Bindu chakra, and the secret of immortality is said to reside there. When Vishuddha is closed, we undergo decay and death. When it is open, negative experience is transformed into wisdom and learning.
