In the very many talks he gave during his lifetime, right up to shortly before his death in 1980, a theme he returned to often was that of the Blessed Virgin Mary.
He had studied everything written about her that he could get hold of. Not content with that he enriched us in those talks by sharing his knowledge with us, most especially the role she plays in bringing us to her Son.
Indeed a couple of his talks on Our Blessed Lady, I believe, give an insight into Our Lady as yet not fully realised by the Church at large. Such was the intimacy, knowledge and love he had of her.
