This modification of the normal, or defensive shield enables a person to allow certain energies in, or allows a person to recharge (intake) using Universal Energies. Please note that modifying a defensive shield for either of these adds inherent weakness to the shield. Modification of your shields for filtering, or intaking is achieved purely through goal visualization. Visualize the filter effect, or energy you wish to allow through your shields. Although this modification adds weakness to a shield it also can drop the amount of energy to maintain a shield because the shield does not have to stop all energy from approaching you, and you can feed the intaken energy directly to your shields to maintain them.
