Indian philosophy isn’t about salvation from samsara in all instances. The Vedic knowledge acts a means to know your true nature. A person maybe or maybe not be motivated by escaping samsara.
I use the word samara here only bc that is the word Richard had used in the link you sent. I am assuming he is referring to the suffering that results from samara. Not samara itself. Samsara means worldly entanglement. So that in itself wouldn’t be a motivate a person to escape, its more escaping suffering that can come from result of actions in samara.
Salvation is seen in Christianity, in that you need saving from descending into hell.
