Aragonite is beautiful grounding stone, and is a reliable earth healer due to its connection to the Earth Goddess.
As it stabilises energy and the base chakra, it is perfect to use during meditation; particularly if working on your inner child or childhood trauma as does so gently.
With its ability to centre and ground physical energies, it is useful in times of stress and has the ability to transmute this energy even at distance.
Aragonite teaches patience and acceptance. It can also be very useful for those who take on too much or push themselves to hard as it encourages delegation.
Blue aragonite is connected to the third eye chakra, and can enhance your ability to communicate (in both your life and with the higher realms), and can strengthen your intuition and psychic abilities.
