Physically it's about being heard and speaking up. We've seen people being really vocal throughout Lockdown, and especially during the protests. And we also witnessed an absence of expression, people going quiet.
The heart chakra is fairly self explanatory. It's about being open hearted. When our first three energy centres are relatively balanced then we can evolve into a truly loving person. We begin to cultivate the deeper qualities of service and compassion.
There's a story of a Zen Master who was given a cut crystal glass by a former student. It was a beautiful object to look at and sip water from. The Master would show the glass to visitors, and tell them about the kindness of his former student.
