SSA ji,
What is Brahman according Advaita philosophy ???
As per my understanding through Gurbani , the whole existence is GOD. both in its Sargun and Nirgun form and governed by Hukum.
The totality of existence is GOD .
Question: did the Guru meditate and enjoin meditation upon his followers?
The brief answer to your question is— Yes. Just read Mandukya upnishad (7th of total 12 mantras).
Here is a detailed answer …
Brahm is that from which this created world arises (Ishopnishad) and into which it dissolves (Kathopnishad). The param Brahma is nirgun-nirakar and out of time, Ishvar (param Brahma + prakriti) is sagun-nirakar, Viraat is the cosmos with time included (all space time).
Hukum might be like “Dharma”, but Param Brahm is the source of Dharma too.
The creation has five aspects: aakash, vayu, agni, aap (“water”), and prithvi. And five Gunas (shabd, sparsh, tej, taste, and smell).
The Sikh shabd might be “Aumkaar”. In Advait, shabd is equated to the immanent universe.
Shabd (possibility, the seed of creation) is the essential attribute of Aakash (space), sparsh of vayu (awareness, non-physical Guna), tej (Revelatory, equates to information) of agni, ras (taste or essence, equates to experience) of water, and gandh (equates to attachment to experience) of earth.
To worship Shabd is to worship Viraat— universe in the expressed and incarnate form. That is the worship shown in the Gita, when Krishna appears in his viraat form to Arjuna. It is the immanent and accessible divinity. According to Gaudapad’s reading of Mandukya, this is the divinity of the waking state. It is the “A” of the aumkara.
In Advait, the three levels of divinity are not hierarchical. No one says that one is superior to another. Ishopnishad clearly asserts that the source and the product are both equally divine (“poorna”).
Aum (the sound, with its silence included) is equated to Parambrahm in Maundukya upnishad. “A” + “U” + “M” + “ ”.
A is the same divinity as the immanent universe. U is the sookshm (सूक्ष्म; non-physical, i.e., informational) universe, but considered created. “M” is the creator, and is depicted as prakriti+brahm (aka Ishvar), and is an obscure concept. It is the result of the power of maya.
The silence that follows AUM (and precedes the next if you’re chanting) is the param brahm.
This mapping or equation of aum to the four realities is for the purposes of meditative attainment of mukti. If you’re not into meditation, all this is irrelevant.
The Wrishis (equivalent to Guru) are revered, but not worshipped. Their authority in spiritual revelation is not challenged, but they are not infallible or divine. They are human, like you and I. They have sex, get angry, forget, etc.
Hope this helps.
I have no intent to influence or convert. Sikhism is a great religion. If a son of mine became a Sikh, I’d love him no less, and maybe the more. If I can say this as a Hindu— wahe Guru. 🕉
