The All pervading Dakshinamoorthy..

The above slokam is from the great

Daksinamoorthy Stotram created by Shankara Bhagavatpada, the Acharya Swami.

The Lord Dakshinaamoorthy shines forth in eight forms that would cover all the moving and non moving objects.. 1 The earth, 2 the water 3. The fire 4. The Air 5.The Sky 6. The sun 7 The moon and 8. The living human self.. There is nothing else existing here apart from the all pervading Supreme one and no one who has the faculty of perception could know of anything other than His form in anything that is manifest in the universe.. Our pranams now here, to that resplendent form of the supreme Guru Dakshinamoorthy

The Ashtamoorthy swaroopa of Lord Shiva and Dakshinamamoorthy reveals that the Lord Himself is appearing in the shape of all moving and immobile things.

Kalidasa in the opening stanza of Abhijnana Shakuntalam too echoed this very same idea with minor variations .

या सृष्टिः स्रष्टुराद्या वहति विधिहुतं या हविर् या च होत्री

ये द्वे कालं विधत्तः श्रुतिविषयगुणा या स्थिता व्याप्य विश्वं

यामाहुः सर्वबीजप्रकृतिरिति यया प्राणिनः प्राणवन्तः

प्रत्यक्षाभिः तनुभिरवतुवः ताभिरष्ताभिरीशः॥

महाकवेः कालिदासस्य अभिज्ञानशाकुन्तळात्॥।

Yaa shrastuH shritiraadhyaa vahati vidhihutam yaahavir yaa cha hotri,

ye dwe kaalam vidhattah shrutivishayagunaa yaa stitaa vyapya viswam,

yaamaahu sarvabhiijaprakrutiriti yaya praaninah praanavanthaH

pratyakshaabhiH tanubhiravatu vaH taabhirashtaabiriisah...

who is the first among creations..water,

who takes oblations properly made to gods..agni,

which is the offering in yajna the havis,

who is the person making oblation.. brahmana,

who knows the past and future.. time,

who is the medium of hearing and sustains the life of all beings..air,

who pervades the whole universe, the teja in the shape of akasha,

and

who as the prakriti is the mother for all beings..the mother earth...

Lord Ashtamurthi the

Shiva who manifests in these eight forms may protect us.

The very idea of Pantheistic forms of the Lord are put forth in the great chapter Shatarudriyam or Sri Rudram appearing in Yajurvedam too..

note 

The Ashtamoorthy tattwa  discussed in  the Dakshinamurthy stotram  I quoted earlier  is intended for the seeker  for Upasana of Sadashiva the Brahmaatmatattva in the following manner

 उपासकः स्वदेहे वर्तमान पञ्चभूतानि व्यष्टिभूतानि समष्टिभूतैः प्राणापनौ च सूर्यशशाङ्काभ्यामेकीकृत्य पञ्चभूतात्मकशरीराभिमानिनं स्वात्मानं अष्टमूर्तिपरमेश्वरेण एकीकृत्य सकलव्यापी अष्टमूर्त्यात्मकः सदाशिवोऽस्मि इति चिन्तयेत्।  ततो भावनातिशयेन तत्सायूज्यं प्राप्य सर्वैश्वर्यसंपन्नो अन्ते तत्प्रसादासादिततत्त्वज्ञानेने तत्त्वसाक्षात्कारेण विमुच्यत इति॥ तत्त्वसुधा  स्वयंप्रकाशयतीन्द्रपादकृतम्॥

upāsakaḥ svadehe vartamāna pañcabhūtāni vyaṣṭibhūtāni samaṣṭibhūtaiḥ prāṇāpanau ca sūryaśaśāṅkābhyāmekīkṛtya pañcabhūtātmakaśarīrābhimāninaṁ svātmānaṁ aṣṭamūrtiparameśvareṇa ekīkṛtya sakalavyāpī aṣṭamūrtyātmakaḥ sadāśivo'smi iti cintayet|  tato bhāvanātiśayena tatsāyūjyaṁ prāpya sarvaiśvaryasaṁpanno ante tatprasādāsāditatattvajñānene tattvasākṣātkāreṇa vimucyata iti|| 

tattvasudhā  svayaṁprakāśayatīndrapādakṛtam||

 The seeker should  consider that the five elements with which his body is made  is in unison with the divine body of Sadashiva consisting of the the five elements pervading everything,  that the prana and apana within him are the Sun and the Moon existing outside as the manifestation of Sadashiva, and that he is identifying himself with the Lord Shiva.  When the seeker contemplates in this manner with utter concentration and sincerity of purpose, He become endowed with the Lordship of everything  and enjoys life when he is alive and finally he becomes the recepient  of all knowledge of truth, which is defined as direct realization,  he attains emancipation or Moksham..

 This is from the commentary of tattwasudha of svayamprakashayateendra
