Samartha Ramdas Swamî was a great Saint from Maharashtra, India. He was the Guru of Shivajî Maharaj, a great and pious king of 17th century Maharashtra. One day, as the king and His Guru were inspecting some construction in the royal palace, the king thought, "Indeed I am a great king, how well I take care of all my subjects!" The Guru, in His Omniscience, read His disciple's thoughts and decided to correct his thinking immediately.
There was a huge boulder nearby. Ramdas Swamî asked some of Shivajî's soldiers to break it into two. When His request was carried out, everyone present witnessed an incredible sight. They saw that the rock had a small water-filled cavity with a little frog in it! As soon as the boulder was split into two, the encaged frog jumped out, breaking free.
Samartha Ramdas Swamî now turned to Shivajî and asked, "If you feel that you are taking care of everybody in this kingdom, pray tell me who was taking care of the frog trapped in the rock?" The king realized his mistake and felt remorse for his egotistical thinking. He realised that it was God Who had created everything and took care of all His creation.
Moral : One should do everything, including spiritual practice, with humility. Spiritual practice done with an attitude of surrender would eventually give the experience of the truth that God alone is Almighty and the Creator of all.
