What is the ultimate, the pristine and pure truth, as per Hinduism?

The pristine and purest Ultimate Truth as per Hinduism is that ‘ALL IS ONE’.

Everything else or other than it, is but an explanation of it. All the scriptures, philosophies, isms etc. of India are but its exposition.

Spiritually of India is thus. More or less.

And for that matter, even scientifically, the ultimate reality is such.

That is, if modern science were to catch up to it - the Absolute of All That Is, as self-realized by the ancient Indian seers and sages. Then, it too would find that there is no other absolute reality than it.

A unified singularity of eternity, unto everything as everything, in indivisible unity, is the eternal reality.

All is an infinite and an indivisible wholeness and oneness.

It is the everlasting truth and reality of each and every little thing. It is the ‘thing’ of things. It is IT!

This eternal, infinite and inseparable immanence of the Whole, is the invincible, indestructible primordial Essence of All.

Call ‘it’ the soul of all, the universal soul, god, or nothing at all. Thus is the nitty-gritty of it all. It is the gist and genesis of the Source et all.

This immanence of permanence runs in the veins as though of the cosmos, the universal phenomena, including the transient and the impermanent.

‘It’ is everything, of everybody.

Of you, and I. And yeah, even of your infidel buddy!

In all simplicity, thus is the quintessential and eternal truth of ‘Sanatana Dharma: the Eternal Religion. And to so seek and find the ‘It’ of Which Is, thus is the pristine and postulated duty and dharma of every Indian - nay! of all people on earth, irrespective of their religion or ism.

It is also simplistically and colloquially referred to as Hinduism.

So, salute the soil of your motherland, where you’re born!

For hither, not thither! You’ll the Truth be shown; which, by the way, to most of the world and to billions of it inhabitants, remains unknown.

One, and oneness is all.

There is nothing more - to seek, or find. So, seek That Which Is. And if it be your karmic due, in this very birth, you’ll find none but One.

Thereafter live and die, accordingly.

Chill out. Say, bye bye birdie!

And you’d have won. Are done!
