Shankara’s Advaita
The Arishadvargas (the six enemies of Man) get a foothold in his mind because it is filled with the darkness of ajnana [ignorance]. They are nocturnal birds like bats and owls that cannot tolerate light. Darkness will not flee if you throw stones at it; nor will it disappear if you lay about it with a sword or shoot it with a gun. It will be destroyed only when a lamp is lit. [Sage] Shankara taught this simple truth to many who were ignorant of this simple fact. The people of this country were lost in the pursuit of many goals because their vision was blurred by darkness. Shankara taught them that the Vedas, Upanishads, and Shastras had but One in view, the One‑without‑a‑second, Advaita.
Shankara, when quite a young boy, was one day offering puja [prayers] to Devi, the household deity, because his father was away and he had asked him to perform worship in his absence. He placed milk before the image and prayed pathetically that She should sip the milk, as he imagined She was wont to do when his father did the puja. He wept so sincerely that Mother melted at his wailing and drank the entire quantity! Shankara had seen his father distribute the milk that was offered to the Mother, a tiny spoonful to every member of the family. But since the cup was emptied in one quaff by Her, nothing remained. The boy feared that he would be blamed for drinking what was the share of the others. So, he wailed again. Devi felt great pity at the plight of Shankara, who had taken the image to be alive, and who had compelled Her already to manifest Herself from it. But she did not pour milk out of Her palm, as I do; she pressed Her maternal breasts and filled the cup. Shankara’s avedana, his anguished yearning, had succeeded in making Devi respond!
Beginners only need image worship
Similarly, the other day Sri Ramamurthy, who is sitting among you here, shouted, “Swami” in sincere faith and agony. His wife was writhing in pain because her clothes had caught fire. She was too panic‑stricken to call out My Name. But this cry was heard by Me. I hurried to the spot, which is, as you say, 400 miles away; I crumpled the fire out before it was too late.
Shankara worshipped images in childhood, and he knew the value of Saguna-swarupa (God as endowed with qualities). He advised Saguna aradhana (worship of the Form) to the large majority of people even later in his life. Little children must be taught with the help of slates and boards on which illustrations are drawn. Temples, images, and pictures are the slates and boards for the children in spiritual progress. But if you play with a toy elephant, you cannot derive the experience of contacting the real one. The Formless can be conceived only when you have transcended the Form.
Shankara’s advaita is the ultimate truth
When Shankara thought of renouncing the world (in order to get the authority to educate it), he felt that his mother’s consent had to be taken for the step. So while bathing in the Poorna River near his house, he cried out one day that a crocodile had caught his leg. It was true, for the crocodile was, as in the Gajendra moksha story, only samsara (worldly life) called by that name, sensual desire, to put it in other words. When the mother came rushing to the bank of the river, he told her that the crocodile would let him off only if he took sanyasa, became a monk! This was also true, for renunciation, detachment, giving up worldly ties, is the means of saving oneself from bondage. The bewildered mother agreed, and the boy left home to seek his guru, and through him the secret of liberation.
Shankara lived only for 32 years, but during that time he purified and consolidated the various schools of worship and brought them under the over‑all care of one philosophical principle, advaita (non‑dualism).
The Mahavakyas (the great statements on Supreme Reality) of the Vedas once again began ringing in the hearts of all, with their true meaning. Aham Brahmasmi; Thath‑thwam‑asi; Prajnanam Brahma (I am Brahman; Thou art That; consciousness is Brahman)—all were explained in simple, convincing logic, in sweet captivating poetry. Shankara’s advaita is the ultimate truth, and so it is only confirmed, not shaken by the discoveries of science or the flights of intellect. It speaks of the unity of matter and energy; of time and space, of the Universe being but Brahman seen through the veil of maya [illusion], which, too, is but an activity of the primordial.
Shankara knew that advaita requires intense sadhana (spiritual effort) that will remove all trace of ego, all idea of duality, from the mind of man. So as a preparatory discipline to the dawn of the awareness of one’s real unity with the substance of the Universe, he taught the rules of yoga and bhakti [devotion] and karma. These, according to him, will brighten the intellect, cleanse the emotions and purify the heart. Advaita is the awareness of the Divine in everything, everywhere, in full measure.
Shankara suggested sathsang (good company) as the very first step in sadhana. The company of the wise and the good will develop into detachment and love of silence and solitude. That will promote the disappearance of moha (delusion), which according to Arjuna [son of Pandava], was the fruit of listening to the Gita. When that happens, one is established steadily in the Tat‑twam, the reality of this and that, the identity of this with that. Well, the recognition of that identity is the attainment of mukti (liberation).
