Ramakrishna Paramahansa Saves a Scorpion
“Once Ramakrishna Paramahansa was walking along with some of his disciples across the river. He saw a scorpion floating on the surface in the river, struggling to survive; it must have been struggling there for some time, so it was trying to get out of there desperately, but in vain, as it was not able to successfully cross the river. When Ramakrishna saw this little creature struggling so hard, his heart melted, he ran into the water and lifted the scorpion, the scorpion which was already scared to death stung him in its fear.
One of the disciples who were watching all of this happen asked his Guru 'O Master! Why did you lift it the second time? Even after it stung you causing so much pain?' The Guru replied 'It is the nature of the scorpion; it will sting us when it is scared. It was struggling, it was in pain; it is my nature to help it. Should I give up my nature Just because it stung me?'
