Space refers to the energy in your surroundings. Your auric field. The size of your aura depends on many things and it can move from a small space when we are down physically, mentally, spiritually to are large space when we are grounded, balanced and flowing. This space can be felt energetically by anyone in your auric field. In certain practices like yoga the instructor, the guide holds the space with their energy. This enables clients to use this safe space to get what they need. Holding space for others takes balance, love and compassion towards oneself and others.
