what i have seen time after time in the synaxarium (official daily comemoration of the saints in the coptic church), in the other stories of the saints and in the films of the saints is that those who experience any supernatural manefestations while praying (light, altered state of consciousness etc.) go to great lengths to hide it.
it seems that genuine supernatural manefestations happen to truly humble people who pursue a deep relationship with God, accepting all kinds of suffering and fleeing from all pride or fame.
we should 'love the lord our God with all our heart, mind, soul and strength' and 'love our neighbour as ourselves', and when these are our primary goals, other blessings follow.
seeking experiences and emotional 'highs' does not bring stillness, rather it comes from a lot of discipline (regular Bible study, getting up early to help your neighbour instead of breakfast in bed, praying all the time) and from consciously accepting to do God's will, even when it results in looking foolish in front of people, or suffering.
so i think we can reach the depth of the love of God that we seek by pursuing our Bible study, prayer, fasting and good deeds with dilligence, and by regular confession and Holy Communion and listening to (and applying) the sermons we hear in church.
