The whole process of transferring oneself to the spiritual sky involves gradually liquidating the material composition of the gross and subtle coverings of the spirit soul. The above-mentioned five items of devotional activities are so spiritually powerful that their performance by a devotee, even in the preliminary stage, can very quickly promote the sincere executor to the stage of bhāva (the stage just prior to love of Godhead), or emotion on the spiritual plane, which is transcendental to mental and intellectual functions. A complete absorption in bhāva, or love of God, makes one fit to be transferred to the spiritual sky just after leaving the material tabernacle. The perfection of love of God by a devotee actually situates him on the spiritual platform, even though he may still maintain a gross material body. He becomes like a red-hot iron which, when in contact with fire, actually ceases to be iron and acts like fire. These things are made possible by the Lord's inscrutable and inconceivable energy, which material science has not the scope to calculate. One should therefore engage himself in devotional service with absolute faith, and to make his faith steadfast one should seek the association of the standard devotees of the Lord by personal association (if possible) or by thinking of them. This association will help one develop factual devotional service to the Lord, which will cause all material misgivings to disappear like a flash of lightning. All these different stages of spiritual realization will be personally felt by the candidate, and this will create in him a firm belief that he is making positive progress on the way to the spiritual sky. Then he will become sincerely attached to the Lord and His abode. Such is the gradual process of evolving love of God, which is the prime necessity for the human form of life.
There are instances in history of great personalities, including sages and kings, who attained perfection by this process. Some of them attained success even by adhering to one single item of devotional service with faith and perseverance. Some of these personalities are listed below.
1. Emperor Parīkṣit attained the spiritual platform simply by hearing from such an authority as Śrī Śukadeva Gosvāmī.
2. Śrī Śukadeva Gosvāmī attained the same simply by recitation, verbatim, of the transcendental message which he received from his great father, Śrī Vyāsadeva.
3. Emperor Prahlāda attained spiritual success by remembering the Lord constantly, in pursuance of instructions given by Śrī Nārada Muni, the great saint and devotee.
4. Lakṣmījī, the goddess of fortune, attained success simply by sitting and serving the lotus feet of the Lord.
5. King Pṛthu attained success simply by worshiping the Lord.
6. Akrūra, the charioteer, attained success simply by chanting prayers for the Lord.
7. Hanumān (Mahāvīra), the famous nonhuman devotee of Lord Śrī Rāmacandra, attained success simply by carrying out the orders of the Lord.
8. Arjuna, the great warrior, attained the same perfection simply by making friends with the Lord, who delivered the message of Bhagavad-gītā to enlighten Arjuna and his followers.
9. Emperor Bali attained success by surrendering everything unto the Lord, including his personal body.
These are nine standard modes of devotional service to the Lord, and a candidate can choose to adopt any one, two, three, four or all, however he likes. All the services rendered to the Absolute are in themselves absolute, with none of the quantitative or qualitative differences found on the material platform. On the spiritual platform everything is identical with everything else, although there is transcendental variegatedness. Emperor Ambarīṣa adopted all the above nine items, and he attained perfect success. It was he who engaged his mind on the lotus feet of the Lord, his voice in describing the spiritual world, his hands in cleansing the temple of the Lord, his ears in submissively hearing the words of Lord Śrī Kṛṣṇa, his eyes in viewing the Deities of the Lord, his body in touching the bodies of the devotees, his nostrils in smelling the flowers offered to the Lord, his tongue in tasting the food offered to the Lord, his legs in visiting the temple of the Lord, and all the energy of his life in executing the services of the Lord without in the least desiring his own sense gratification. All these activities helped him attain the perfect stage of life which defeats all dexterities of material science.
It is therefore important for all human beings to adopt these principles of spiritual realization for the perfection of life. A human being's only obligation is spiritual realization. Unfortunately, in modern civilization, human society is too busy in discharging national duties. Actually, national duties, social duties and humanitarian duties are obligatory only to those who are bereft of spiritual duties. As soon as a man takes his birth on this earth, not only does he have national, social and humanitarian obligations, but he also has obligations to the demigods who supply air, light, water, etc. He also has obligations to the great sages who have left behind them vast treasure-houses of knowledge to guide him through life. He has obligations to all kinds of living beings, to his forefathers, family members and so forth and so on. But as soon as one engages himself in the one single obligatory duty—the duty of spiritual perfection—then he automatically liquidates all other obligations without having to make separate efforts.
A devotee of the Lord is never a disturbing element in society—on the contrary, he is a great social asset. Since no sincere devotee is attracted to sinful actions, as soon as a man becomes a pure devotee he can do inestimable selfless service to society for the peace and prosperity of all concerned, in this life and in the next. But even if such a devotee commits some offense, the Lord Himself rectifies it in no time. Therefore, there is no need for a devotee to cultivate materialistic knowledge, nor does a devotee need to renounce everything and live as a hermit. He can simply remain at home and execute devotional service smoothly in any order of life. And there are instances in history of extremely cruel men becoming kindhearted simply by the execution of devotional service. Knowledge and abnegation of an inferior way of life follow automatically in the life of a pure devotee without his having to make extraneous effort.
This spiritual art and science of devotional service is the highest contribution of Indian sages to the rest of the world. Therefore everyone who has taken his birth in India has an obligation to perfect his life by adopting the principles of this great art and science and distributing it to the rest of the world, which is still ignorant of the ultimate aim of life. Human society is destined to reach this stage of perfection by gradual development of knowledge. Indian sages, however, have already reached that position. Why do others have to wait for thousands and thousands of years to attain their heights? Why not give them the information immediately in a systematic way, so that they may save time and energy? They should take advantage of a life for which they may have labored millions of years to attain.
