If one wants to go to the higher material planets, he can keep his finer dress of mind, intelligence and ego, but has to leave his gross dress (body) made of earth, water, fire, etc. When one goes to a transcendental planet, however, it is necessary to change both the finer and gross bodies, for one has to reach the spiritual sky completely in a spiritual form. This change of dress will take place automatically at the time of death if one so desires. But this desire is possible at death only if the desire is cultivated during life. Where one's treasures are, there also is one's heart. When one practices devotional service, one cultivates a desire for the kingdom of God. The following details outline a general practice by which one can prepare himself for an easy journey to the Vaikuṇṭha (antimaterial) planets, where life is free from birth, old age, disease and death.
General practice (positive functions):
1. The serious candidate must accept a bona fide spiritual master in order to be trained scientifically. Because the senses are material, it is not at all possible to realize the Transcendence by them. Therefore the senses have to be spiritualized by the prescribed method under the direction of the spiritual master.
2. When the student has chosen a bona fide spiritual master, he must take the proper initiation from him. This marks the beginning of spiritual training.
3. The candidate must be prepared to satisfy the spiritual master in every way. A bona fide spiritual master who is fully cognizant of the methods of spiritual science, learned in the spiritual scriptures such as the Bhagavad-gītā, Vedānta, Śrīmad-Bhāgavatam and Upaniṣads, and who is also a realized soul who has made a tangible connection with the Supreme Lord, is the transparent medium by which the willing candidate is led to the path of the Vaikuṇṭhas. The spiritual master must be satisfied in all respects, because simply by his good wishes a candidate can make wonderful progress along the path.
