The following is respectfully quoted from “A Spacious Path to Freedom” by Karma Chagme with commentary by Gyaltrul Rinpoche
Lord Gampopa says of the tradition of the practice lineage:
If a spiritual mentor lacks realization, it does not help even if his disciples act with reverence and devotion. As an analogy, although the clay may be good, if its mold has no indentations, it will not form into a statue. If the disciples have no reverence or devotion, it does not help even if the spiritual mentor has realization. This is like a cow having milk, but its calf having no palate.
