Recognising one’s error is the first excellence of a good disciple; it is the beginning of wisdom. Only the foolish will feel they know all and suffer from the dire disease of a swelled head. (GV, p. 17)

Consciousness of Deva instead of Deha, of God instead of body, will bring forth the splendour of Prema. Light is wisdom. Without light, all is darkness. (JV, p. 35)

The wisdom of the Bharatiya is nourished by Dharma. (SV, p. 149)

Wisdom flashes like lightning amidst the clouds of the inner sky; one has to foster the flash, and preserve the light. That is the true sign of the educated person. Wisdom can grow only where humility prevails. It thrives when man is afraid of vice and sin, and is attached to the Divine in himself and in all else. The crisis of character, which is at the root of all the troubles everywhere, has come about as a result of the neglect of this aspect in education. (SSS Vol. 10, p. 3)

Wisdom is the precious ambrosia gathered from all sources of knowledge and all the arts of earning it. It is the sweet, sustaining butter churned and collected from the Shastras. Wisdom is not to be defined as the capacity to discriminate and declare ‘this is flat’, or ‘this is round’, or ‘this is a hill’, ‘this is a house’, or ‘this is a thorn’. That is the common belief. This is only knowledge. Next, we have what may be called good knowledge (Sujnana), when man is able to distinguish between right and wrong or good and bad, when he can discover, ‘this activity is for my betterment and the betterment of others’. Both Jnana and Sujnana are confined to the intellect of man. There is a higher stage called Vijnana, when the heart is transformed by loyalty to Truth, Non-violence and Compassion. Such a person can understand himself, his kinship with the cosmos, and with the Creator of the cosmos. He lives in accordance with that understanding, without doubt or disharmony.Ajnana, or ignorance, breeds sorrow; Vijnana confers joy. If one hesitates to call any experience Vijnana, let him examine whether it is material or spiritual, on the touchstone, ‘does it give me unalloyed joy?’ and then classify it as such: The yardstick for Vijnana is Dharma. The more Dharma is put into practice, the more one gets rooted in Vijnana. Action through Vijnana is evidenced by the peace and prosperity of the nation. The decline of Dharma reveals the disappearance of Vijnana. (SV, p. 148)

Veda is Wisdom; Wisdom is God. (SSS Vol.7, p. 321)

You must be able to distinguish between wise action and unwise action and for that you must understand the difference between wisdom and ignorance; Sakhya refers to the mergence of wisdom with wisdom, which means developing the individual wisdom and then merging it with the cosmic wisdom. Any one who wants to directly experience the Lord must develop this wisdom; and along with it a number of important qualities. The Characteristics of a person endowed with spiritual wisdom, the Sthitaprajna, are patience, determination, purity of the body and mind, selfless love, an ever present awareness, and yearning for the Lord, and the six qualities which are known as the spiritual treasures, namely Sama, control of the mind,Dama, control of the senses,Uparati, which is the sacred feeling that comes from renunciation of desires,Titiksha, endurance and indifference to all kinds of opposites such as pain and pleasure;Shraddha, an unshakable faith; and Samadhana, the unwavering concentration and contentment derived from equipoise of the mind. (DBG, pp. 237-238)

Detachment and renunciation do not spring up suddenly to become the foundations of Atma jnana; they do not just happen on the spur of the moment. These qualities must be steadily developed and practised, together with devotion and self-control. If you want to light a lamp, you will need oil, a container to hold it and a wick. In the same way, in order to light the lamp wisdom, there is a need for detachment, devotion and control of the senses. Detachment can be thought of as the container and devotion the oil. The control of the senses may be compared to the wick. By bringing together these three elements, it is possible to light the lamp of the inner Self. In order to light the lamp of the heart ofArjuna,Krishna warned him that he must first control the sense organs. (DBG, p. 126)

When you have attained true wisdom, you will find that good fortune should not be gloated over, nor bad fortune grieved over. The Hero treats both with equal unconcern. They are breezes and storms that cannot affect the depths of the Ocean of Bliss in the heart of Man. (SV, p. 3)

There is a lot of difference between the words Wisdom and Jnana. Knowledge is what is within certain limits. This knowledge is worldly and it is bookish and superficial, but Wisdom is something, which is Divine. We cannot compare both of them. Wisdom is also explained as Sva Shakti. Sva Shakti is that flower emanating from the heart. This knowledge can be obtained from books, teachings, or from any other thing. It is possible to fill something in a head, which is empty. But in a head filled with all sorts of things without emptying it can we fill it with something? (M, p. 29)
