How does a person connect and integrate with air to develop and expand spiritual energy? You can focus your attention and mind to connect with the energy of air when you are outside and feeling the wind touching your skin. If you travel by airplane, you can use those moments to engage in meditations and sense the change in energy when you connect with the air rather than ground with the earth, for example.
During moments when you focus your attention on the air around you, you are able to use this focus and combine it with the energy the air can provide. This process and connection, along with the sensation being created, will help stimulate the expansion and use of this energy.
