Yes ! All actions happen in the regime of Prakruti (Apara Prakruti)

Yes ! All actions happen in the regime of Prakruti (Apara Prakruti) ! In Purusha there is not any action. But when any sin or virtue takes places, Self (Jeevatma/ Purusha/ Para Prakruti) experiences the results thereof. Yes ! It is the car which runs. The Driver does not run. But when any accident takes place, car is not punished, the Driver is punished.Kalpanaji ! 5 causes referred by you are in BG 18:14 not in 18:15 to 17. One of the 'cause' is 'Karta' (Doer) ! Jeeva becomes that 'karta' by 'acceptance' and hence suffers punishment. When 'Karta' viz Jeeva renounces the wrong 'acceptance' and admits 'I am not Karta'- he ceases to be 'Karta' and ceases to be sinful (18:17). It is all "accepted doership" not "actual doership" !! Actually there no doership in Jeeva. "Actual doership' is only in Prakruti (BG 13:20) !! "Punishable/ rewardable/ relevant doership" is "assumed doership" not "actual doership" !! Gita saying that Pure soul is not Karta is right. Jeeva is not Karta but 'accepts' to be Karta and thus artificially becomes a Karta. Without an "assumed" Karta an "activity" can place, but not "Karma". Hence there is no inconsistency in Gitaji. Sadhak Ramakrishna is right. Gitaji is right. Sadhak Basudeb Sen is also very right in his message. In fact Purusha ( Para Prakruti) who is part of God, forms affinity with Apara Prakruti (inert) ! Not only that, he in affinity with inert also 'creates' an independent entity of him'self' as "Prakrutishtha Purusha" ( BG 13:21- Jeeva ) ... Which creation is called 'Aham' ( ego as stated by Basudebji Sen ) ! In this 'Aham' (Jeeva) , both sentient and inert are there. The modification (vikaar) of happiness/sorrow takes place in inert portion only , but the "effect/result" of the same is on 'knower' sentient portion !!! In other words, sentient (chetan) 'assumes/accepts' that sorrow/happiness modification as taking place in him'self' !! Just as while fever comes in body, we say " I am
feverish" ! In fact when you realise that "I am not doer" then you are neither karta nor bhokta. ( BG 13:31) ! Thereafter , whatever "activities" take place in the body of Doershipless/ Suffershipless ( Kirtitva/bhktritva rahit) Jeeva are caused by "Aham vritti" (ego) ! The activities done by this "aham" is stated in Gita by various ways. Say in 13:29 by Prakruti; in 3:27 by Gunas of Prakruti; in 3:28 by Gunas interplay with Gunas; in 14:29 by Gunas and in 5:9 by stating senses are consuming in senses. Meaning thereby that whatever activities take
place by internal "karanas" and external "karanas" , are all by Prakruti.
