Bhagavad Gita means Song of the Spirit, the divine communion of truth-realization between man and the Divine, the teachings of spirit through the soul. It is a comprehensive metaphysical and psychological profound scripture that describes all experiences that will come to the spiritual traveler on the path.
Around the time when the book (poem) was written, asceticism was seen in India as the ideal spiritual life. Ascetics from different sects all agreed that leaving everything behind (family, possessions, occupations, etc.) was the best way to live in a meaningful way.
The plot is based on two sets of cousins competing for the throne. Diplomacy has failed, so the two clans’ armies meet on a battlefield in order to settle the conflict and decide which side will gain the throne. Krishna sees Arjuna quitting and begins to persuade him. Suggests that he should stick to his duty as a warrior and engage the enemy. The Bhagavad Gita is presented as a conversation between Arjuna and Krishna, a man and a god, a seeker and a knower.
The main metaphor of the Gita is the battlefield, the cosmic conflict between good and evil: life as a series of battles between spirit and matter, soul and body, life and death, knowledge and ignorance, health and disease, changelessness and transitoriness, self-control and temptations and so on. It also explains the three paths of yoga to a great relationship to the three gunas. The three aspects of the mind: sensory mind, ego mind and intellectual mind (buddhi). Krishna says: I m in all the gunas but the gunas are not in me. The Bhakti yoga path is applicable to sattva when we feel aspiration, the luminous quality. The Jnana path of knowledge would assist to maintain the rajas state. In the tamas state we want to get into the action (Karma) yoga aspect, the pranayama aspects and bring pratyahara to meditate and be able to disengage from the senses. To give up selfish desire. Krishna says to Arjuna : you cannot be attached to inaction. That means we have to keep being active into the field of life. We cannot be attached to the outcome of actions. We need to do what it takes for the highest good. To surrender to the inner guide (the inner guru).
The Bhagavad Gita questions how can someone live a life spiritually meaningful without withdrawing from society and what can someone who does not want to give up family and social obligations do to live the right way?
