Sensuality, creativity, enthusiasm, exploring creativity and boundaries.
15-21 and 64-70 Third/Solar Plexus Chakra
Development of personality and feelings, wisdom, expansion and limitless possibilities.
22-28 and 71-77 Fourth/Heart Chakra
Love, compassion, selflessness, development of healing skills in self and others, working to heal the earth.
29-35 and 78-84 Fifth/Throat Chakra
Communication, self-expression, inspiration, independence, openness to higher development, speaking with wisdom
36-42 and 85-91 Sixth/Brow Chakra
Realization of inner senses, such as clairvoyance, intuition, responsibility, deepening life experiences
43-49 and 92-98 Seventh/Crown Chakra
