They understand that there is no end to problems in this world, and that these problems change colour and complexion like the proverbial chameleon. These are the people who have tried all the tricks in their bag to secure unalloyed happiness in this world and ultimately failed. They have come to realise the deceptive attractiveness of the worldly objects. They have experimented and found for themselves that a change of place or circumstance or environment in this world does not produce a lasting change for the better, but only resembles a change from the frying pan to the fire. Every thing and every place is fraught with misery.
Every worldly experience is conditioned by suffering and exertion.
These are the people who are qualified to become students of the school of spirituality. They are the Sadhaks or the spiritual seekers or the spiritual aspirants proper. A spiritual aspirant is one who feels himself in a state of bondage. That is not enough for a spiritual aspirant. He must get fed up with everything in Samsara.
