Bhakti is a real, genuine search after God, a search beginning, continuing and ending in love. One single moment of madness of extreme love to God brings us eternal freedom. Devotional service is a process of spiritual understanding. Wherever devotional service exists, the material contamination cannot coexist. The book Bhakti - Devotion discusses Bhakti using various approaches. These include:
a) Collection of Sayings from the Shastras. The ancient Hindu Shastras such as the Vedas, Upanishads, Mahabharata, Ramayana, Puranas, Bhagavad Gita, Shrimad Bhagavata, etc., contain invaluable Sayings which are a source of enlightenment.
b) Sage Naradas Bhakti-aphorisms. Sage Narada describes Bhakti as intense love to God; when a man gets it, he loves all, hates none; he becomes satisfied for ever.
c) A discussion of Bhakti-Yoga - The Path of Devotion, Chapter 12 of the Bhagavad Gita. This chapter takes us deeper into the concept of Bhakti.
d) Bhaktas - Devotees of the Lord. Their lives are a source of inspiration and instill in us a sense of devotion.
e) Shri Adi Shankaracharyas devotional song Bhaja Govindam. It is enchanting and elevates the mind to a higher plane.
f) Sanskrit Epithets of Lord Krishna and Arjuna used in the Bhagavad Gita. There is great depth in their meanings.
