The idea behind "Way to Home" is to achieve freedom from the cycle of life, death, and rebirth and the suffering that comes along with that cycle.
In Saiva Siddhanta true liberation is a gift from God and the result of his direct intervention. When the Souls are immersed in maya, they learn about the unreal from the unreal. What they learn is basically theoretical knowledge or lower knowledge. It does not help them to transcend their conditioned minds and experience their true consciousness. It is only when Lord Siva bestows his grace upon them and comes to them in the form of a personal guru, the Souls overcome their illusion and realize their Siva consciousness.
