Each one has to answer this question for oneself. There is no use gaining entry into institutions of Yoga by filling up a form and remitting five rupees of admission fee. The fitness does not consist merely in thinking that you have to gain admission into an Ashram. The fitness does not consist in a feeling of defeatism, frustration and grief at home. Sorrows are not necessarily the only qualification for aspiring after the goal of Yoga.
Yoga is the most positive of truths.
Any negative pre-condition cannot become a qualification for its practice. Quarrels at home, demotions in office, loss of property, death of children, cannot become qualifications for Yoga. But most people are qualified only in this way. That is the reason why they have no peace of mind even though they sit before a great saint. They come with an internal disturbance, sit before holy audiences with a disturbed mind, and sit also with no clear notion as to the goal.
