Wherever there is instruction to be got there is an ashram. And whenever you go there you will get instruction from the experiences of life. Therefore the whole world is an ashram to a discerning student. Much the same applies to the question of a teacher. Says a Bengali verse: "Wouldst thou make obeisance to thy master, my heart? He is there at every step, on each side of thy path. The welcome offered thee is thy master, the agony inflicted on thee is thy master. Every wrench at thy heartstrings that maketh the tears flow is thy master."
