Sadhanas (practice) differ according to the stage of evolution, the strength of ego, weaknesses and the nature of the lower Self. A strong and sturdy constitution and a fine health are in themselves a good qualification for the student. All other qualifications can be developed when one is placed in favourable environments. In the spiritual path any type of student can progress and evolve if he is endowed with Sraddha, sincerity and faith. There is no need for special talents or qualification. There is no need also for a deep study for years and Japa on one leg for decades. A willing, loving heart is what is needed. The student must have a new angle of vision and try to crush the ego at each step by discipline, discrimination and dispassion. Charge the mind with Divine Consciousness through constant Japa, prayers and systematic meditation.
