Srimad Bhagavad Geeta/Srimad Bhagavatam
Srimad Bhagavad Gita is the philosophical teachings of Lord Krishna, delivered as a sermon to Arjuna just before the Kurukshetra war and it's a part of Mahabharata.
While Srimad Bhagwatam is a grand collection of Puranas and spiritual stories with lots of philosophical teachings too. It includes the stories of Bhagavan Vishnu's 24 avatars and stories of several great devotees.
The key distinction lies in the fact that Bhagwatam is the word of god whereas Bhagavad Gita is essentially the conversation between Krishna and Arjun, which can be imagined as a conversation between an educator and a student.
Bhagavad Gita embraces the philosophy of Karma Yoga and Jnana Yoga.
The Bhagavad Gita is a philosophical discourse that describes how a person's soul (called the "atman") can be liberated from attachment and desire, and then bring that consciousness to bear upon the deeds of one's life. Although some aspects of the teachings are rather obscure, it is clear that Krishna intends to convey something about human psychology, consciousness, and action. The main message of the Bhagavad Gita is summed up in Krishna's statement in verse 48.9: "the learned do not call it a deed; for none is the agent here nor enjoyer of the fruits thereof. He who sees inaction in action and action in inaction, he is wise among men.
In the Bhagavad Gita, we come to know about Krishna as a diplomat, who imparts his knowledge to Arjuna. But in the Bhagavatam, Krishna appears in his divine roles and avatars as well as his various manifestations.
In addition to enlightening us through the divine visions, Lord Krishna talks about the three paths of action, karma yoga, jnana yoga, and bhakti-yoga. On the other hand, Srimad Bhagavatam acquaints us with Krishna's childhood and teenage.
The Bhagavat Gita - also called the Gita, is a 700-verse scripture in the Sanskrit language. It is best known as a discourse given by the Supreme Being Krishna to Arjuna during the Bhagavad Gita War. The Gita has been one of the most widely translated works in world literature. As of 2014, it has been translated into over 50 languages and is reportedly the most translated religious book in the world. Shrimad Bhagwatam is also known as Srimad Bhagavata Purana, or simply as Bhagavata, is one of Hinduism's eighteen great Puranas. Unlike many of the most popular Puranas, it does not glorify the Hindu god Vishnu alone but expands upon stories of other devotees of Vishnu as well.
The Bhagavatam is divided into 12 parts which are called the skandha. The Bhagavatam starts with the creation of the world, the reasons for which it was created, and then moves on to the Narayan Purusha and his avatars. It gives details of the avataras of the Vishnu and Deva-Deva wars. The various other topics discussed include The nature of god/Brahma, The nature of Atman, the path of devotion, Karma throughout one's life, and a summary of all Hindu scriptures.
Unlike the Mahabharata which has many philosophical depths to it which is generally accepted as the most complex text ever written in human history. The Bhagavatam is a Spiritual text that focuses on personal devotion to Vishnu. The core philosophy of this text is completely different from that of the Mahabharata.
