When buddhi tries to think about something(like solving a problem using logic) does it use the mann to do the thinking part or does the thinking happen in buddhi itself (meaning mann and buddhi work independant of each other while performing rational thinking). So for example, we know one can witness one's mind having vrittis(thoughts). But when one decides to think about something rationally then : Does it happen in the buddhi itself while mann is still doing its thing of creating vrittis and because the person is focused on the rational thinking he ceases to recognise the vrittis occuring in mann OR Does buddhi use the mann to perform rationaly thinking thereby preventing mann from creating any vritti during this time?
In other words : Is mann, the equipment used for performing both kinds of thinking : rational (driven by buddhi)/irrational (mann itself) OR Is buddhi the equipment for rational thinking while mann is the equipment for irrational thoughts (vrittis) ?
TLDR :
Buddhi -> creates logical vrittis in the mind -> using such logical vrittis in the mind, buddhi arrives at a logical conclusion -> mind instructs the karmendriyas (action senses) to take action accordingly
OR
Buddhi -> creates logical thoughts in itself -> reaches a logical conclusion in itself -> provides logical conclusion to mind -> mind instructs the karmendriyas (action senses) to take action accordingly ?
