The left heart is home to our spirit, or the purest uncorrupted form of ourselves. When this chakra is clear we connect to our spirit, and are free from identifications with our thoughts or emotions. In life, we tend to tie our identity to our job, country, city, mood, or education, rather than our true selves.
When we are connected to our spirit or true self, we no longer rely on our circumstances or surroundings to achieve happiness. Rather, we are in a completely detached and self-sustaining state of bliss, nourished entirely from within. In this way we are able to feel pure love for everyone, which gives without condition or motive.
