When Bhagavan was in Virupaksha Cave, Echamma, who installed a picture of Bhagavan and a picture of Seshadri Swami in her house, decided to do puja with a lakh of tender leaves, and began it after informing Bhagavan about it. By the time she had finished the puja with fifty thousand leaves, summer had set in, and she could not gather any more leaves even though she wandered all over the mountain. She got tired, and went to Bhagavan to ventilate her grievances. Bhagavan said, “If you cannot get the leaves, why not pinch yourself and do puja?” She said, “Oh, but that will be painful!” Bhagavan said, “If it pains you to pinch your body, is it not painful to the tree when you cut its leaves?” She turned pale and asked, “Why did you not tell me earlier, Swami?” He replied, “When you know that pinching the body is painful, why did you not know that the tree will be equally pained if you rob it of its leaves? Do I have to tell you that?”
That tender leaves should not be cut from trees is also stated in the sloka in “Devikalottara Stotra” in Jnanachara Vicharapadalam, given below:
Roots should not be pulled out. Leaves should not be pinched. Living beings should not be harmed. Flowers should not be plucked.
