Swami Sivananda dressed to clothe himself, ate to live, and lived to serve humanity. A small dilapidated Kutir (hut), not resorted to by others and infested with scorpions, protected him from rain and sun. Living in that Kutir, he did intense Tapas (austerities), observed silence, and fasted. Often he fasted for days on end. He would keep a good stock of bread in his room, and for a week have this, together with Ganges water. He would stand up to the hips in the ice-cold Ganges in winter mornings and commence his Japa, coming out only when the sun appeared. He would spend more than twelve hours in daily meditation. With all his intense Tapas, Swamiji did not neglect service of the sick. He visited the huts of the Sadhus with medicines, served them, and shampooed their legs. He begged food on their behalf and fed them with his own hands when they fell sick. He brought water from the Ganges and washed their Kutirs. He attended upon cholera and small-pox cases. If necessary, he kept vigil through the night by the side of the bed of the ailing Sadhu. He carried sick persons on his back to the hospital. With some money from his insurance policy that had matured, Swamiji started a charitable dispensary at Lakshmanjula in 1927. He served the pilgrims and saw Narayana in them.
Swamiji practiced all the various Yogas and studied the scriptures. After years of intense and unbroken Sadhana, he enjoyed the bliss of Nirvikalpa Samadhi. He had come to the end of his spiritual journey.
