RishiRahul=Let us take an extreme case of courage... the brashness of love/love heroic deeds tinged with rashness. Here that passion(venus mars) ruled by the heart overpowers the mind (moon). Again both heart/mind performs here.
Then the other opposite is people who are timid. Here the mind is overactive/calculating the consequences of the youthful heart.
A 'deed' performed requires action. Action requires courage. Courage requires the play between the mind and the heart in differing proportions. This difference denotes the type of courage or 'khaleja' in colloquial terms.
This is why I said that the heart is the source of courage. Then the filtering of the mind comes. The result is 'deed'.
Saturn conjunct moon, particularly, when linked to the house of courage leads to events happening in the course of life when a time comes that mind tries to filter the efforts from happening with confidence.
Sometimes...... the earlier life had some overconfident brash moves leading to dissapoint.
This can happen in navamsa too involving dharma(question of right/wrong).

i get what you say, and the part regarding Saturn conjunct or linked to moon is very true . it gets filtered to the extent that sometimes it is nullified.
also i have a chart where Rahu is conjuct moon in the third house of cancer not aspected by any planet and retro Guru in the 4th house aspected by Shani in 2nd house and Mangal from 1st house
the native is courageous but in a satwik way and very true to heart and fight for the noble and right cause.
i am starting to get what you mentioned.
RishiRahul=Now I know what you mean and would like to know!
Saturn in the vikrama vhava makes the native gain courage through inner realisations. This is particularly so if he has Saturn in the 3/6 from Al. The realisation becomes very internal, and long and hurtful if Saturn is afflicted. In your case it is afflicted in navamsa by moon, the karaka of mind.
Do understand that realisation is an internal ingredient for courage.... particularly when it is internal courage given by Ketu or Saturn.

in my case saturn is 6th from AL and afflicted as you said
and it is the most hurtful. this courage i am talking about is not for proactive things but things which are reactive like mostly dealing with people, the reaction to this hurt is further hurt as there is no exhaust , i mean a tit for tat or something like that. its only staying silent brooding and feeling and etc.
Yes Saturn is weak in cancer and in 6-8 relation with Moon, afflicted in navamsa by moon.
Also i always thought aspect of Mars(high in shadbala) from 12th was a major factor for this supression of expression of courage.
i didnt know moon played a vital role
