"How many" or "how much" is asking about the quantity of something - the number of things there are in that group.
"mani" literally means "jewel". Spiritually it means wisdom. To gain wisdom (not worldly or academically knowledge) you need to be sharp (focus / concentrated); like a sword which can cut through darkness or ignorance, you need to be pure at heart ( a sinful mind is deluded and hence unable or guilded to be focus) which can evolved to higher consciousness and thereby able to journey inwards to realise the true nature of things; to return to the source, the TRUE NATURE. You can expand the word "mani" or wisdom to many, many realisation which is only possible if you can meditate and realise; you cannot gain the meaning by reading what people have written or listening to what people are telling you - these people are writing or telling their perceptions of what they know or came across and not your realisation of what you are ignorant of.
