Without spiritual intelligence or wisdom, love is often improperly expressed, akin to spoiling one's children. It is possible for one to love in the wrong way, to give of oneself indiscriminately to others without thinking how it could possibly damage the educational, learning experience that their souls are striving to master.
 
The evolution of others may be delayed by loving them wrongly and unthinkingly--and yet, one must love. Love should not only be unconditional--it should be enlightened--and this requires intelligence and wisdom.

It takes a developed intelligence to delve into the mysteries of God and Nature and to make contact with the Powers directing Her (nature). Without the influx of the intelligence of the Spirit one remains intellectually blind. The intelligence/wisdom-consciousness empowerment assists the recipient to embrace and unfold a greater degree of intelligence; it infuses into the lower mind, the divine force of the Higher Ego.

The more developed one's intelligence, the greater the opportunity, capacity, and ability for one to accelerate one's progress spiritually and mundanely.
