Lord Krishna says: ~It is only one amongst thousands of people who strive for spiritual salvation.+

By worshipping a God in human form, repeating mantras is like watering barren soil.  The seeker of truth should not waste life in empty formalities. Without realizing the world in which he exists is an illusion it is impossible to acquire Self-knowledge or Brahma Gnana or Atma Gnana.

In Bhagavad, Gita Krishna says: ~It is only one amongst thousands of people who strive for spiritual salvation. Even amongst such seekers, it is only the rare person who gets to know “Self” correctly.’ (7.3)

Mundaka Upanishad:~ The rituals and the sacrifices described in the Vedas deal with lower knowledge. The sages ignored these rituals and went in search of higher knowledge. ... Such rituals are unsafe rafts for crossing the sea of samsara, of birth and death. Doomed to shipwreck are those who try to cross the sea of samsara on these poor rafts. Ignorant of their own ignorance, yet wise In their own esteem, these deluded men Proud of their vain learning go round and round Like the blind led by the blind.

How can you worship the Absolute? That implies two ~ the worshipper and the worshipped, whereas the Absolute is nondual. One can worship his idea of the Absolute only or realize his unity with it when he can’t worship it as apart.

Religious rites and rigid ceremonies were passed down from one generation to the next as a practice or set customs and tradition and performed automatically with blind faith. Such worship based on the belief of God does not reach God.

Religious rites and ceremonies, yagnas and homa-havans, or any other forms of ritual are meant for the ignorant populace.

Belief in God without knowing God in actuality holds the worshiper more firmly in the grip of ignorance. 

All worship and the ceremonies rituals performed on the base of non-~Vedic Gods will not yield any fruits.  Deeper self-search reveals the fact that worshiped, the worship and worshiper, and the world are merely an illusion created out of consciousness.

Religious rites and ceremonies, yagnas and homa-havans, or any other forms of ritual are meant for the ignorant populace. In the Atmic path, the seeker has to discard what is not needed to realize the truth, which is beyond the form, time, and space.

Religious rites and ceremonies, yagnas and homa-havans, or any other forms of ritual formal observance have long since set in. 

Sage Sankara says: ~ “The scriptures dealing with rituals, rewards are therefore addressed to an ignorant person.  -Adhyasa Bhashya 

Sage Sankara:~ (11) As regards the rituals, Sage Sankara says, the person who performs rituals and aspires for rewards will view himself in terms of the caste into which he is born, his age, the stage of his life, his standing in society, etc. In addition, he is required to perform rituals all through his life. However, the 'Self' has none of those attributes or tags. Hence, the person who superimposes all those attributes on the changeless, eternal Self and identifies Self with the body is confusing one for the other; and is, therefore, an ignorant person. The scriptures dealing with rituals, rewards, etc. are therefore addressed to an ignorant person. -Adhyasa Bhashya 

Sage Sankara:~ (11.1) This ignorance (mistaking the body for Self) brings in its wake a desire for the well-being of the body, aversion for its disease or discomfort, fear of its destruction and thus a host of miseries(anartha). This anartha is caused by projecting karthvya(“doer” sense) and bhokthavya (object) on the Atman. Sankara calls this adhyasa. The scriptures dealing with rituals, rewards, etc. are, therefore, he says, addressed to an ignorant person. -Adhyasa Bhashya 

Sage Sankara:~ (11.2) In short, a person who engages in rituals with the notion “I am an agent, doer, thinker”, according to Sage Sri, Sankara, is ignorant, as his behavior implies a distinct, separate doer/agent/knower; and an object that is to be done/achieved/known. That duality is avidya, an error that can be removed by Vidya. -Adhyasa Bhashya

Sage Sankara: ~ (12) Sage Sri, Sankara affirming his belief in one eternal unchanging reality (Brahman) and the illusion of plurality, drives home the point that Upanishads deal not with rituals but with the knowledge of the Absolute (Brahma Vidya) and the Upanishads give us an insight into the essential nature of the Self which is identical with the Absolute, the Brahman. -Adhyasa Bhashya 

Sage Sankara: ~ Atman, the innermost Self is verily Brahman (God), being equanimous, quiescent, and by nature absolute Existence, Knowledge, and Bliss. Atman is not the body that is non-existence itself. This is called true Knowledge by the wise.  

Advaita is not a theory or a philosophy. Advaita is the nature of the Soul the innermost Self.  There is no need for any theory or philosophy or scriptures to acquire Self-knowledge. Only a perfect understanding of ‘what is what’ is needed.

Sage Sankara: ~ 'Like a servant who carries a lamp in front of you to find your way, and you have found it, so becomes the Veda to that person. What is the Veda? ~ utterances of those who have known the Truth. Here is one who has known the Truth; why should he or she depend upon the Veda further? Actual realization takes you beyond books. At a certain stage, books become a botheration. The Upanishad itself says that the 'words are only so much of distraction for such minds'

Bhagavan Buddha: ~ “Do not believe in anything merely on the authority of your teachers and elders”.

You need not become a Guru or a monk to acquire Self-knowledge or Brahma Gnana or Atma Gnana. You have not to renounce the world or to leave anything ~ your wife, children, job, responsibilities. You do not have to renounce anything! The only thing you have to realize is the truth, which is beyond the form, time, and space by realizing form, time and space are the product of ignorance. When the ignorance vanishes, the unreality of the form, time, and space is exposed.

Upanishad says:~  "He who thinks he knows, does not know." This means that to know anything implies a second, an object of knowledge, hence duality, i.e. no Gnana.

Tripura Rahasya: ~ Second-hand knowledge of the Self-gathered from books or Gurus can never emancipate a man until its truth is rightly investigated and applied; only direct realization will do that. Realize yourself, turning the mind inward. (18: 89) : ~ Santthosh Kumaar
