Attachment for the Supreme can be increased by practicing devotional service, inquiring about the Supreme Personality of Godhead, applying bhakti-yoga in life, worshiping the Yogesvara, the Supreme Personality of Godhead, and by hearing and chanting about the glories of the Supreme Personality of Godhead. These actions are pious in themselves.
