If we are around age 30-35, mai tu liao (don't procrasinate further). Take them as good example. By 30 plus they had achieved great in spirituality. So lets spend some time in spiritual studies now. Don't wait until ganna traffic accident or other accident, die suddenly and then become wandering sinkie ghost. Or until 70-80 plus, mind blur liao, eyes blur liao, cannot read or study liao then start to think about spiritual matter...
