These interviews have some really great stuff; though my one issue is with the interviewer's portrayal of Ven. Ñānānanda as being considered a 'heretic' - where I feel Bhikkhu Yōgānanda is looking for drama where there is none. As far as I know, Bhante Ñānānanda is thought of very highly by almost everyone who's familiar with him. If there's a reason he's not as well known as some other monks in Sri Lanka (i.e. outside the circles of more 'serious' Buddhists) it's due to the limited circulation of his books rather than him being considered a heretic.
"Delighting in existence, O monks, are gods and men; they are attached to existence, they revel in existence. When the Dhamma for the cessation of existence is being preached to them, their minds do not leap towards it, do not get pleased with it, do not get settled in it, do not find confidence in it. That is how, monks, some lag behind."
