Why does an active worldly person lose interest in worldly action and become inactive upon turning spiritual?

[An online spiritual discussion was conducted on November 01, 2020, in which several devotees participated. Some of the questions of devotees answered by Swāmi are given below.]

[Śrī Bharat Krishna asked: Usually, a worldly person is very active. But when he starts learning spiritual knowledge, he or she becomes inactive for a while. This is because the person realizes that he was going in the wrong direction so far and also, that he is unable to develop devotion due to some doubts that he still has. Hence, he is unable to do either worldly work or spiritual service and sacrifice (karma yoga). During this transition period, the person becomes inactive and suffers for not being able to perform well in spiritual or worldly life. Is there any way to avoid this?]

Swāmi replied: A person correctly understanding the true spiritual knowledge preached by Sadguru will not become inactive, but will become more active in both worldly life and spiritual life. Arjuna became inactive due to his wrong understanding of spiritual knowledge and he became active due to the true spiritual knowledge preached to him by the Sadguru, Kṛṣṇa. He became very active in worldly life immediately after the preaching, due to which, he fought the war. After the war, he also became very active in the spiritual line. In his next birth, he was born as the hunter, Kaṇṇappa, who worshipped the statue of God Śiva and who plucked out his eyes for the sake of God Śiva. In the next birth, he was born as Swāmi Vivekānanda, in which He attained final salvation upon serving the contemporary Human Incarnation, called Śrī Rāmakṛṣṇa Paramahaṃsa.
