Advaita Siddhānta (doctrine) is about the Knowledge of the Self—the one and only “substance” that is eternally present, immutable, infinite, and complete, lacking nothing. It is no exaggeration to say that the most fundamental prerequisite for correctly understanding this millennia-old pinnacle of human thought known as Advaita Vedānta is humility.
Śaṅkara Bhagavatpāda beautifully summarizes the means to grasp Advaita Siddhānta in a single sentence in his commentary on Bhagavad Gītā 18.50. He adds that this is the very message conveyed by Śrī Kṛṣṇa in Bhagavad Gītā 2.69 and at several other places. He writes:
“It is only a cessation of the perception of the differentiated forms of the external world that can lead to a firm grasp of the real nature of the Self.”
Śaṅkara is equally careful to point out that Self-knowledge remains unattainable for those:
— who have not been properly initiated into the traditional teaching by the Gurus (the Great Ones);
— who have not studied the teachings of the Vedānta;
— whose intellect is deeply engrossed in the objects of the senses; and
— who have not been trained in the proper means of knowledge.
One of the most essential qualifications for assimilating the Advaita teaching from a Guru is śraddhā on the part of an earnest seeker. Unfortunately, there is no English word that exactly captures the meaning of śraddhā.
Śraddhā signifies, at once, unwavering attentiveness to the Guru’s teaching and confidence in oneself to recognize the truth of what is being taught. It should not, however, be mistaken for blind faith.
Even before śraddhā, however, a seeker must possess humility. Śaṅkara states in Upadeśa Sāhasrī (Prose 1.1.5) that qualities such as humility are among the means to attaining Self-knowledge.
Lord Kṛṣṇa instructs Arjuna to approach a Guru with an attitude of service in order to receive Advaita jñāna (Bhagavad Gītā 4.34). Here, “service” does not imply servility or a slavish mentality. Rather, it signifies an attitude of humility.
The Śruti conveys the same message. It asks the seeker to approach the teacher samitpāṇiḥ (Muṇḍaka Upaniṣad 1.2.12)—with sacrificial faggots in hand—symbolizing complete humility and receptivity.
Advaita Vedānta is not a dogma. Questions born of a sincere spirit of inquiry are not merely welcome; they are actively encouraged. But questioning that is intended only to display intellectual pride or egoistic arrogance betrays a lack of humility and serves no useful purpose. Such an attitude is best avoided.
