Because WE (human BEings) have forgotten who we are, we were taught to believe Life ends after Death. Belief can be dangerous because it makes matters true for you yet it may not be True in deed which explains the fear of Death.
Unless and until Truth is remembered then recognized for what it Really is rather than what it should've, could've or would've been, Suffering will appear in endless forms as a result of Denial. Denial, is the main cause of Suffering because it turns a "blind eye" to Truth and whenever Truth is forgotten, Suffering is not far behind.
Because Truth is what it is - always was and will always BE - there is nothing to teach considering Truth does not change, ever! Because Truth is not of this world, everything known as Truth is not Truth but just a cheap version of it made up by ego which explains the fear of Truth. We've been led to believe, by ego, that Truth hurts, when in fact the complete opposite it True - lies hurt, Truth heals.
Truth is, WE (human BEings) are LOVE, we simply forgot. Because WE (human BEings) are not of this world, Life does not end, PERIOD. Death is the end of birth, Life has no end because LOVE has no beginning and no end. As long as there is LOVE, there is Life and considering only LOVE is Real, there is nothing to fear.
Remember this, LOVE is fearless and Whole, needing or wanting nothing but to expand itself through the expression of the human experience. Time is never an issue when it comes to LOVE, because LOVE doesn't depend on Time. Because Time is of this world, it is guaranteed to no one. In spite of this fact, unless and until WE (human BEings) are ready and willing to "die" to self aka ego, Life after Death will continue to a topic of discussion rather than the "BEST experience to be had!"
Die to self/ego and BE Life/LOVE. Peace
