Concentration and Meditation by Swami Paramananda explains the importance of controlling the mind and directing its power towards spiritual growth. The book teaches that concentration develops through regular practice, self-discipline, purity of thought, and detachment from distractions. By gathering scattered mental energies and focusing them on a single object or ideal, one can achieve greater clarity, peace, and efficiency. Meditation deepens this process, helping the aspirant discover the divine presence within and realise the higher nature of the Self. The author emphasises patience, perseverance, sincerity, and a calm, balanced life as essential foundations for spiritual practice. The book offers practical guidance for overcoming mental restlessness and cultivating inner harmony, self-awareness, and spiritual realisation. It encourages readers to make concentration and meditation integral parts of daily life.
