He who, while living in this physical body, does not practise Yoga, is living merely for the sake of sensual enjoyments. The world you reach after the body is shed is determined by the level of the consciousness reached while in the body. What makes an ascetic great is his holiness and humility. It is not the capacity to do clever conjurer's tricks or dream hysteric dreams, but it is to remain pure from lust and resentment, passion and desire. This living martyrdom is ever so much more difficult than killing oneself.
Death is easy.
It is life that is taxing. Every thought projected from every brain goes on pulsating, as it were, until it meets a fit object that will receive it. A sensible person shall not proclaim others' faults. An intelligent man shall not speak words wounding the hearts of others. It is only your inner teacher that will walk with you to the goal for he is the goal.
