One observation that I have learned from the Holy Spirit is that its identity is not abstract dogma(mysticism). Speaking to the Holy Spirit offers us divine effectiveness in daily matters. A keen penetration or discernment;
"There is no Muslim who calls upon his Lord with a dua in which there is no sin or severing of family ties, but Allah will give him one of three things: Either He will answer his prayer quickly, or He will store (the reward for) it in the Hereafter, or He will divert an equivalent evil away from him." [At Tirmidhi].
