The Tapas and the other hard Yogas that were practiced in other Yugas do not work now. What is needed in this Yuga is giving, helping others.
Swami VivekanandaGreat work requires great and persistent effort for a long time. ... Character has to be established through a thousand stumbles.
Swami VivekanandaBy practice men can bring even the heart under control, until it will just beat at will, slowly, or quickly, or almost stop. Nearly every part of the body can be brought under control.
Swami VivekanandaSay So'ham, So'ham whatever comes. Tell yourself this even in eating, walking, suffering. Tell the mind this incessantly-that what we see never existed, that there is only I. Flash-the dream will break! Think day and night, this universe is zero, only God is. Have intense desire to get free.
Swami Vivekananda
