The word practical means "applied, not merely theoretical." Thus, practical spirituality is something experienced and lived.

Instead, you will learn how to work with spiritual facts to expand your perception of reality, and transform your experience of living, by setting aside harmful and useless behaviors, and adopting behaviors that benefit yourself and others.
“Even if one is the most sinful of all sinners, one shall yet cross over the ocean of sin by the raft of Self-knowledge alone. As the blazing fire reduces wood to ashes; similarly, the fire of Self-knowledge reduces all bonds of karma to ashes...” — Krishna, Bhagavad-gita 4:36-37
"We should not mistake the Truth with opinions. Many think that the Truth is this or that, or that the Truth is within this or that book, or within this or that belief or idea, etc. Whosoever wants to experience the Truth should not mistake beliefs, ideas, opinions and theories with that which is the Truth. We must experience the Truth in a direct, practical and real manner; this is only possible in the stillness and silence of the mind, and this is achieved by means of meditation."
