Transpersonal chakras are a line of several chakras (various authors describe either three, five, or six) that many yogis and meditation practitioners say are located sequentially above the crown chakra (itself located on the top of the head) to a distance above the head of as far as about 18 inches (about 0.5 meters).
Transpersonal chakras in Asian philosophy
Transpersonal chakras are seen in Hinduism, in Vajrayana Buddhism, in Daoism and in qigong, and in New Age thought as several chakras above the head, as noted above. The transpersonal chakras in Hinduism have Sanskrit names, in Varjayana Buddhism they have Sanskrit and Tibetan names, and in Daoism and in qigong they have Chinese names. There are five transpersonal chakras above the head beyond the usual seven that are mentioned and named in the esoteric texts of Vajrayana Buddhism.
New Age three transpersonal chakra system
Using the New Age names, the lowest transpersonal chakra (the soul star chakra) is said to be located about 4-5 fingers above the head, the middle transpersonal chakra (the God portal chakra) is said to be located about 12 inches above the head and the highest transpersonal chakra (the Grand Portal chakra) (sometimes called the stellar portal chakra} is said to be located about 18 inches above the head. 
The soul star chakra
The soul star chakra is a chakra that many meditation practitioners say is located above the crown chakra. The soul star chakra is said to be located about 4-5 fingers above the head. This chakra is associated with spiritual connection between individuals, as well as connection to one's Higher Self. 
Function of the transpersonal chakras
The highest transpersonal chakra is called the "grand portal" because it is believed by some mystics, magicians and yogis to provide access for soul travel into other parts of this universe, into alternate universes, to higher planes of existence, to the past or future history of our own timeline or alternate timelines via time travel forward or backward in time, or to other cosmoses.

- See the 1937 book Star Maker by Olaf Stapledon for a science fiction account of such a journey via soul travel; although the book does not mention anything about chakras, the book does mention the spiritual range that various alien races that are encountered within the Milky Way Galaxy and the Magellanic Clouds are capable of, which is roughly equivalent to the concept of "chakras".
