Bhakti Yoga is the term used in Hinduism to define the spiritual practice of fostering loving devotion to God, also called bhakti. The Bhagavad Gita is considered the cornerstone for Bhakti Yoga. Bhakti Yoga is mostly associated with the Hare Krishna movement, however, it is also present within other Yoga traditions and is especially performed during the festivities dedicated to the Gods. In Sanskrit Bhakti is the term used that signifies a blissful, selfless and overwhelming love of God, that finds its personification in the people surrounding us (family and friends).

'Bhakti-rasamrita-sindhu' (written by Rupa Gosvami) gives the following as the nine primary activities of bhakti, with the instruction that by following all, or just one, of these activities perfectly the aspiring devotee can achieve pure love of God:

Hearing about the Lord - singing & chanting God's names (japa), hearing stories from scripture.
Glorifying the Lord - describing God's all-attractive features.
Remembering the Lord - internal meditation on the Lord's form, activities, names or personality.
Serving the lotus feet of the Lord - providing a form of physical service.
Worshiping the Lord - deity worship (puja) is a popular form of this within India.
Offering prayers to the Lord - any form of prayer offered to please God.
Serving the Lord - offering a service for Lord's pleasure, such as preaching activity.
Building a friendship with the Lord - having an internal, loving relationship with God.
Surrendering everything unto the Lord - surrendering one's thoughts, actions and deeds to God.

These nine principles of devotional service are described as helping the devotee remain constantly in touch with God.

The scriptural source of these nine primary forms of bhakti is a verse in the Bhagavata Purana, spoken by Prahlada:

"Prahlāda Mahārāja said: Hearing and chanting about the transcendental holy name, form, qualities, paraphernalia and pastimes of Lord Viṣṇu, remembering them, serving the lotus feet of the Lord, offering the Lord respectful worship with sixteen types of paraphernalia, offering prayers to the Lord, becoming His servant, considering the Lord one's best friend, and surrendering everything unto Him (in other words, serving Him with the body, mind and words) — these nine processes are accepted as pure devotional service. One who has dedicated his life to the service of Kṛṣṇa through these nine methods should be understood to be the most learned person, for he has acquired complete knowledge.

More than anything else Bhakti Yoga is a state of mind and a longing of the soul for the divine. You can easily incorporate the principles of Bhakti Yoga into your everyday life, by being loving towards other people, animals and nature and by being appreciative and grateful for everything that life offers you. By adopting a loving mindset towards everything you will experience inner peace and serenity.

To make it easier for you to maintain a "loving mindset", just keep the following in mind; "Look at the world with love, and the light of reason will illuminate your path".
