Prana loka introduces prana, the language of life energy used in the board's yogic framework. Here it is a spiritual model for reflecting on vitality and attention, rather than a measurement of physical energy.
You might notice what makes you feel engaged: meaningful work, contact with others, movement, rest or an idea you want to pursue. The experience can vary from day to day and need not be turned into a test of how well you are living.
Consider where your attention goes willingly and where it feels continually pulled away. There may be a practical adjustment to make, or simply a pattern worth understanding before deciding what to change.
