Krishna is the most popular avatar of Lord Vishnu. He is worshipped mainly in four forms Bala Krishna, Sri Krishna or Rajagopala, Santhana Gopala and Parthasarathy.

The form of Krisha worshipped by GSBs in Kerala are mainly Balagopala, Santhanagopala and Sri Krishna. Lord Krishna appeared over five thousand years ago in Mathura, India to Devaki and Vasudeva in the jail cell of the tyrant Kamsa. He appeared with His brother Balarama in response to the demigod's prayers for protection from the widespread influence of demonic administration on earth. The demons invaded the earth by discretely taking birth as princes in powerful royal families of the time.

And as the earth became overrun by militaristic activities of these kingly demons, the demigods including the Earth goddess earnestly sought Lord Visnu's protection. Seeing the deteriorating social and political conditions, the all-compassionate Supreme Lord Sri Krishna decided to descend for the benefit of all.

Through His famous  Bhagavat-gita, He spoke of the science of yoga in all its forms-the path of work, the path of knowledge, the path of mysticism, the path of devotion.

Sri Krishna's Life Timeline

Bhagavat Gita

The Supreme Lord descends from time to time in this material world to re-establish the teachings of the Vedas. Lord Krishna promises: "Whenever and wherever there is a decline in religious practice, O descendant of Bharata, and a predominant rise of irreligion - at that time I descend Myself. To deliver the pious and to annihilate the miscreants, as well as to reestablish the principles of religion, I Myself appear milleniumm after millenium."  Lord Krishna spoke about the meaning of life, the subtle workings of creation, and the understanding of a self- realized soul.

Summary of Gita

Chapter One:  Observing the Armies on the Battlefield of Kurukshetra.

As the opposing armies stand poised for battle, Arjuna, the mighty warrior, sees his intimate relatives, teachers and friends in both armies ready to fight and sacrifice their lives. Overcome by grief and pity, Arjuna fails in strength, his mind becomes bewildered, and he gives up his determination to fight.

Chapter Two: Contents of the Gita summarized.

Arjuna submits to Lord Krishna as His disciple, and Krishna begins His teachings to Arjuna by explaining the fundamental distinction between the temporary material body and the eternal spiritual soul. The Lord explains the process of transmigration, the nature of selfless service to the Supreme and the characteristics of a self-realized person.

Chapter Three: Karma-yoga.

Everyone must engage in some sort of activity in this material world. But actions can either bind one to this world or liberate one from it. By acting for the pleasure of the Supreme, without selfish motives, one can be liberated from the law of karma (action and reaction) and attain transcendental knowledge of the self and the Supreme.

Chapter Four: Transcendental knowledge.

Transcendental knowledge - the spiritual knowledge of the soul, of God, and of their relationship - is both purifying and liberating. Such knowledge is the fruit of selfless devotional action (karma-yoga). The Lord explains the remote history of the Gita, the purpose and significance of His periodic descents to the material world, and the necessity of approaching a guru, a realized teacher. 

Chapter Five: Karma-yoga - Action in Krishna Consciousness.

Outwardly performing all actions but inwardly renouncing their fruits, the wise man, purified by the fire of transcendental knowledge, attains peace, detachment, forbearance, spiritual vision and bliss.

Chapter Six: Dhyana-yoga.

Ashtanga-yoga, a mechanical meditative practice, controls the mind and senses and focuses concentration on Paramatma (the Supersoul, the form of the Lord situated in the heart). This practice culminates in samadhi, full consciousness of the Supreme.

Chapter Seven: Knowledge of the Absolute.

Lord Krishna is the Supreme Truth, the supreme cause and sustaining force of everything, both material and spiritual. Advanced souls surrender unto Him in devotion, whereas impious souls divert their minds to other objects of worship.

Chapter Eight: Attaining the Supreme.

By remembering Lord Krishna in devotion throughout one's life, and especially at the time of death, one can attain to His supreme abode, beyond the material world.

Chapter Nine: The most confidential knowledge.

Lord Krishna is the Supreme Godhead and the supreme object of worship. The soul is eternally related to Him through transcendental devotional service (bhakti). By reviving one's pure devotion one returns to Krishna in the spiritual realm. 

Chapter Ten: The Opulence of the Absolute.

All wondrous phenomena showing power, beauty, grandeur or sublimity, either in the material world or in the spiritual, are but partial manifestations of Krishna's divine energies and opulence. As the supreme cause of all causes and the support and essence of everything, Krishna is the supreme object of worship for all beings.

Chapter Eleven: The Universal Form.

Lord Krishna grants Arjuna divine vision and reveals His spectacular unlimited form as the cosmic universe. Thus He conclusively establishes His divinity. Krishna explains that His own all-beautiful humanlike form is the original form of Godhead. One can perceive this form only by pure devotional service.

Chapter Twelve: Devotional Service (Bhakti-yoga).

Bhakti-yoga, pure devotional service to Lord Krishna, is the highest and most expedient means for attaining pure love for Krishna, which is the highest end of spiritual existence. Those who follow this supreme path develop divine qualities.

Chapter Thirteen: Nature, the Enjoyer and Consciousness.

One who understands the difference between the body, the soul and the Supersoul beyond them both attains liberation from this material world.

Chapter Fourteen: The Three Modes of Material Nature.

All embodied souls are under the control of the three modes, or qualities, of material nature: goodness, passion and ignorance. Lord Krishna explains what these modes are, how they act upon us, how one transcends them, and the symptoms of one who has attained the transcendental state.

Chapter Fifteen: The Yoga of the Supreme Person.

The ultimate purpose of Vedic knowledge is to detach oneself from the entanglement of the material world and to understand Lord Krishna as the Supreme Personality of Godhead. One who understands Krishna's supreme identity surrenders unto Him and engages in His devotional service.

Chapter Sixteen: The Divine and Demoniac Natures.

Those who possess demoniac qualities and who live whimsically, without following the regulations of scripture, attain lower births and further material bondage. But those who possess divine qualities and live regulated lives, abiding by scriptural authority, gradually attain spiritual perfection.

Chapter Seventeen: The Divisions of Faith.

There are three types of faith, corresponding to and evolving from the three modes of material nature.   Acts performed by those whose faith is in passion and ignorance yield only impermanent, material results, whereas acts performed in goodness, in accord with scriptural injunctions, purify the heart and lead to pure faith in Lord Krishna and devotion to Him.

Chapter Eighteen: Conclusion - The Perfection of Renunciation.

Krishna explains the meaning of renunciation and the effects of the modes of nature on human consciousness and activity. He explains Brahman realization, the glories of the Bhagavad-gita, and the ultimate conclusion of the Gita: the highest path of religion is absolute, unconditional loving surrender unto Lord Krishna, which frees one from all sins, brings one to complete enlightenment, and enables one to return to Krishna's eternal spiritual abode.
