On the relationship between the 5 elements and 7 chakras

After having recently completed the series of compositions for the 5 elements (earth, water, fire, air and aether), I realized that there's a connection to the 7 chakras.

1. Muladhara (मूलाधार) - Earth (saj dhaj dhara aaj - Raga Saraswati)
2. Swadhishtana (स्वाधिष्ठान) - Water (savan ghanana ghanana - Raga Miyaa-ki-Malhaar)
3. Manipura (मणिपूर)- Fire (dani tadani dani - Raga Gujri Todi)
4. Anahata (अनाहत)- Air (aaj pavan karat shor - Raga Madhukauns)
5. Vishuddha (विशुद्ध) 6. Ajna (आज्ञा) and 7. Sahastrara (सहस्रार)- Aether (Om mani kamal vyom - Raga Malkauns)

Om Mani Kamal Vyom - Nirguni Bhajan in Malkauns

ॐ मणि कमल व्योम
सकल ब्रह्मांड चैतन्यरूप
सच्चिदानंद ॐ … ॥ धृ ॥

तन अनेक पर मानस एक
जग दरपन अंतर्मन देख
नित्य निर्गुण निराकार ॐ … ॥१॥

अहंकार आत्मन झगड़े
द्वैत नही तब द्वंद्व मिटे
अद्वैत अमित अनाहतनाद रंगी ॐ … ॥ २ ॥

Explanation -

This is a Nirguni Bhajan in Raga Malkauns. It also embodies the 'Akash Panchamahabhoota' or the element of Space/Sky/Aether.

Om, the cosmic sound (the jewel), creates the universe (the lotus) and fills all of space. (Also see Om-Mani-Padme-Hum).
The cosmos is constructed from consciousness.
This blissful experience of the boundless, pure consciousness is Om.

The 'many' have but one soul.
The world is just a reflection of our inner self.
Om alone is timeless, epithet-less and formless.

The ego is in conflict with the soul.
Conflict ends only when this duality ends.
Only Om, the infinite, spontaneous sound is 'Advait' (indivisible , absolute oneness)
