According to Śaṅkara-sampradāya, everyone must take first of all sannyāsa. Sannyāsa means this renounced order of life. There is no question, those who are enjoying this material life, for them to understand Śaṅkara philosophy. It is another foolishness. Śaṅkara does not recognize anybody who has not accepted sannyāsa. That is his first principle.
So Śaṅkara-sampradāya, they perform very austere penance and principles. They take three times bath at least, three times. And no clothing; simply one loincloth, one . . . and their possession is one loincloth and one wooden water pot. That's all. Nothing more. And they will lie down on the floor. So they are strict, I mean to say, renounced order is very strict.
