Śrīmad-Bhāgavatam
[Canto 2, Ch. 5]
tattva.  As such, Lord Kṛṣṇa is described in the  Brahma-saṁhitā  as the cause of all causes, and this is confirmed in the  Bhagavad-gītā  as follows:
ahaṁ sarvasya prabhavo mattaḥ sarvaṁ pravartate iti matvā bhajante māṁ budhā bhāva-samanvitāḥ.  (Bg. 10.8)
The qualities of sense perception are fully represented in the earth, and they are manifested in other elements to a lesser extent. In the sky there is sound only, whereas in the air there is sound and touch. In the fire there is sound, touch and shape, and in the water there is taste also along with the other perceptions, namely sound, touch, shape, etc. In the earth, however, there are all the above-mentioned qualities with an extra development of odor also. Therefore on the earth there is a full display of variegatedness of life, which is originally started with the basic principle of air. Diseases of the body take place due to derangement of air within the earthly body of the living beings. Mental diseases result from special derangement of the air within the body, and as such the yogic exercise is specially beneficial to keep the air in order so that diseases of the body become almost nil by such exercises, and when properly done the duration of life also increases, and one can have control over death also by such practices. A perfect  yogī  can have command over death and quit the body at the right moment, when he is competent to transfer himself to a suitable planet. The  bhakti-yogī , however, surpasses all the  yogīs  because, by dint of his devotional service, he is promoted to the region beyond the material sky, and he is placed in one of the planets in the spiritual sky by the supreme will of the Lord, the controller of everything.
