The main theme of Sant Tukaram's poetry is devotion and surrender to God. He was a prominent poet-saint of the Bhakti movement, which emphasized the importance of personal devotion and love in one's spiritual journey. Through his powerful and emotive poetry, Sant Tukaram expressed his deep love and devotion for Lord Vitthal, a form of Lord Krishna.

One of the key aspects of Sant Tukaram's poetry is his belief in the path of Bhakti, which he saw as the most direct and accessible way to connect with God. He saw God as a loving and compassionate figure, rather than a distant and fearsome deity. This is reflected in his poetry, where he often addresses God as a friend or a beloved, and expresses his longing to be united with Him.

Sant Tukaram's poetry also focuses on the concept of surrender, or complete submission to God. He believed that by surrendering oneself to God, one could attain true happiness and inner peace. This theme is evident in his famous poem, "Abhanga," where he writes, "I have surrendered my mind and body to you, O Lord, and I am at peace."

Another important theme in Sant Tukaram's poetry is the rejection of societal norms and rituals in favor of a personal and heartfelt connection with God. He criticized the rigid and hierarchical caste system, and encouraged people to focus on their inner devotion rather than external rituals and customs. This message of inclusivity and equality is still relevant in today's society.

In addition to devotion and surrender, Sant Tukaram's poetry also touches upon the idea of detachment from worldly desires and attachments. He believed that true devotion to God requires detachment from material possessions and the ego. This idea is reflected in his poem, "I am not attached to anything, I am not bound by anything, I am not afraid of anything, I am not dependent on anything, I am free."

Overall, Sant Tukaram's poetry is a beautiful and sincere expression of his devotion to God and his teachings on the path of Bhakti. His words continue to inspire and guide people towards a deeper understanding of spirituality and a closer connection with the divine.
