The word ‘jnana’ means knowledge. Knowledge is viewed by the Hindu scriptures as both liberating and binding. Knowledge is viewed as the means to achieve certain ends. It can be used to fulfill our desires or liberate ourselves from the cycle of births and deaths.

The knowledge that helps us realize our selfish desires and perpetuate our limited identities is considered lower knowledge. It is also termed as avidya or ignorance. The knowledge that helps us overcome our egoistic attitude and desires and realize who we are is considered higher knowledge or the real knowledge.

Real knowledge liberates us from the three impurities of human existence, namely egoism, desire ridden actions and the illusion that we are different from the rest of the world and that the objective reality which we experience through our senses is real and permanent.

Janana Yogais the type of self realization. This process involves the higher wisdom or final direct realization of the essential unity of existence.

Jnana yoga is therefore the pursuit of true knowledge by learning how to control our minds and senses and center ourselves in our spiritual selves so that we can become free from our bondage to the cycle of the births and deaths and achieve liberation.

The Bhagavadgita identifies jnana yoga as one of the three main paths to liberation, the path of knowledge, the path of action and the path of devotion. While the path of devotion is described as superior to the other two, jnana yoga is suitable for people who are deeply intellectual. On the path of liberation it is important to possess right knowledge, which comes through the study of the scripture and helps us understand the significance of other yogas such as karma yoga, sanyasa yoga, buddhi yoga, atma samyama yoga, and bhakti yoga.

Janana Yoga is the process of direct experience not to know the result conceptually. Thus janan yogi too reaches that some supra-state in which he becomes identified with all living beings amidst which he lives and moves about, he becomes a lighthouse for illuminating the path for the ship of human life that is caught in turbulent sea of endless conflicts & tensions, to the safe anchorage of limitless peace & bliss.

Janan Yoga is the path of intellect. The way of logical faculty is called Buddhi. We use the power of discrimination of janana yoga to get the reality. The purpose of jnana yoga is to achieve liberation by realizing our true nature, overcoming our ignorance and transcending our limited selves, which are sense dependent and bound by karma. According to the Bhagavadgita, following are some of the developments that we experience when we practice jnana yoga.

1. Equanimity of the mind (sthithadhi) through control of the senses and desires and mental discipline.
2. Detachment (asangatva)
3. Impassion (virag)
4. Tyaga (sacrifice)
5. Renunciation (sanyasa)
6. Self-control (samyama).
7. Devotion (bhakti).

The second chapter of the Bhagavadgita is known as Jnana Yoga or Samkhya yoga. According to some scholars it is a summary of the Bhagavadgita itself since it contains all the important concepts and ideas of the scripture. It reminds us that we should not identify ourselves with our minds and bodies as we are immortal, spiritual beings and that to transcend our limited nature we have to gain control over our sense organs and our desires through detachment and equanimity and work for our salvation by performing actions for the sake of God. According to the Bhagavadgita, jnana yoga consists of the following practices.

1. Developing correct awareness of the mind, the body and the Atman or Self.
2. Stabilizing the mind in the Self through self-discipline and self-absorption (atma-samyamyoga)
3. Acquiring true awareness of the world around and the SUPREME-Self beyond (knowledge of Sat (Truth) and Asat (Falsehood) through discernment (buddhi yoga).
4. Practicing various disciplines and other techniques as a means to self-purification, the predominance of sattva and suppression of rajas and tamas..

Perfection in jnana yoga leads to devotion. Only a jnani, or the knower of the Self, can be a true devotee. People who do not possess true knowledge of the Self, cannot experience the devotion of the highest kind, which the Bhagavadgita extols in several verses. Since they not yet fully free from desires and attachments their devotion remains tainted with traces selfishness and the impurities of rajas and tamas. When the heart and minds are pure, filled with the effulgence of sattva, true devotion arises in them.

The Bhagavadgita suggests various alternatives regarding the regaining of knowledge. Its emphasis, however, is on self-purification and cultivating discernment. In the seventh Chapter, Lord Krishna explains two types of knowledge. One is the knowledge of God and Self (para) and the other is the knowledge of Nature or his lower Self (para). True knowledge according to the scripture is the knowledge of the Self, or the knowledge that leads to liberation. It is acquired in one or more of the following ways. They are all aspects of self-purification, whereby the impurities surrounding the Self are cleansed and removed and the mind becomes sharp.

1. Self-study(swadhyay), which is the study or recitation of the scriptures or any religious or spiritual literature.
2. (Tap)Austerities, rules and restraints which are helpful to remove the impurities of rajas and tamas, whereby one is freed from egoism, strength, pride, lust anger, attachment to worldly possessions and ownership and becomes qualified to reach the state of Brahman (brahma bhuya).
3. Karma yoga, which is performing desireless actions as an offering to God. It will cleanse the mind and body and remove the impurities where intelligence grows.
4. (Dhyana Yoga)Meditation and contemplation upon God or Self, which will help the mind stabilize in the contemplation of God and see things clearly.
5. Identifying oneself with the eternal Self rather than the mind and body whereby one overcomes fear of death and attachment to the body.
6. (Sambhav)The practice of sameness, detachment and renunciation of worldly pleasures which will free the mind from desires and expectations and discern truth.
7. (Remove Karmashaya)The merit accumulated in the past births. As the scripture declares among thousands of men, only a rare person strives for perfection. Again of them only a few succeed. Only at the end of many births does a knower of the Self (janavan) surrender to God.
8. (Ishwar Pranidhan)Devotion to God. Lord Krishna states that he does not illuminate all. Only those who perform pious actions and whose sins are washed away, and who worship him with devotion, knowing that he is the master of elements, master of divinities and master of all sacrifices, they know everything about Brahman, the Self and about karma.

     9. (Satya)The practice of truthfulness, which means commitment to truth in word and deed. When the mind is established in truth, it will discern truth.
