This is the same process you’d use for Infusing an Astral Chakra. The key here is specificity of intention and hand placement. Your intention is to gather a ball of prana, as it is the appropriate resource for working in the Etheric body. Your hand placement is directly on the Etheric chakra, which may well be in the same place as an Astral chakra. Intention plays a role in delivering the energy to the appropriate chakra. Stay focused on the task, and you’ll infuse an Etheric chakra with ease.
