The book describes meditation as the final spiritual discipline leading to the realization of God. However, meditation is only effective when the mind is properly prepared through a foundation of virtue and the rejection of worldly attachments. Practicing virtue to shift focus from the temporal to the eternal. Engaging in Karma-yoga, Bhakti-yoga, and Jnana-yoga to prepare the mind for deep practice. A core focus on Patanjali’s Raja-yoga (from Yama to Samadhi) as the universal background for spiritual life.While Vedanta adopts Patanjali's practical methods, it rejects his dualistic philosophical framework.
