In this entry from “May I Answer That?” Swami Sivananda answers the questions – What are the marks of spiritual progress? How can I know whether he is advanced in the spiritual path or not?
Peace, cheerfulness, contentment, dispassion, fearlessness and an unperturbed state of mind under all conditions indicate that you are advancing in the spiritual path.
Spiritual progress is not measured by Siddhis or powers, but only by the depth of your bliss in meditation.
These are sure tests of your spiritual progress: Is your interest in inner spiritual activity and outer Sadhana increasing day after day?
Does spiritual life mean to your consciousness a matter of great delight, a delight far transcending the happiness that the world of vital pleasures affords you or offers you?
Has your personal awareness come to a possession of a sense of peace and strength which men who are not aspirants do not find in their everyday lives? Do you feel certain that your power of discrimination and light of thought have been steadily growing? Is your life being gradually led to such experiences which reveal to you the operation of a will and intelligence other than your own, the will and intelligence of the Omnipotent Lord?
Has there come into the conscious activities of your everyday life, the active function of a new delightful angle of vision, a new perspective, a strong sense of self-possession, a steadily growing convinction of your dependence upon and intimate relation with the all-pervading Divinity?
If your answers to all these questions or to any one of them are in the affirmative, be absolutely sure that you are progressing, and progressing speedily, in the spiritual path. ~ Swami SIvananda
