Intellect

G-d created man with intellect and the ability to abstract and reason. The person committed to truth would be wise to use the intellect carefully, and make sure that his/her emotions are always in line with reason. Animals act from instinct, pagans mimic animals. The intelligent being recognizes that he is distinct from the animals. Free will is the domain of man alone, the ability to choose between good or evil, to sanctify one's being or debase the gift that was given to him/her by the Creator. Abusing one's body and/or mind with drugs, gluttony, pleasure-seeking, and other forms of irresponsible behavior are akin to killing oneself, from a philosophical perspective. Only rational man is capable of discovering truth. Those who  fixate on primitive superstitions, "mystical movements", and other "New-Age" forms of idolatry, destroy their souls and distance themselves from the Creator. There is a G-d. An omnipotent Being (so to speak) who created the universe and everything contained within. Only those rational people who commit themselves to genuine truth, will merit to find it.
