Sleep and Material Suffering

A diseased person mind in deep sleep forgets his material suffering and pain he is undergoing. Similarly the vedas provides a simple solution towards bliss for all i.e control of Mind. 

In Sri Bhagavad Gita; Sri Krishna says 

Bg 6.5

uddhared ātmanātmānaṁ
nātmānam avasādayet
ātmaiva hy ātmano bandhur
ātmaiva ripur ātmanaḥ

One must deliver himself with the help of his mind, and not degrade himself. The mind is the friend of the conditioned soul, and his enemy as well.

The Process of control of mind is called Yoga which is the subject matter of discussion in Sri Bhagavat Gita wherein Sri Krishna illustrates different types of Yoga and finally culminates with the Supreme type of Yoga i.e Bhakthi Yoga and Saranagathi.

A person whose mind is absorbed in devotion to the Supreme Lord Sri Hari and his topics does not feel the pangs of sufferings of the material world and thus becomes transcendental to its sufferings in the form of janma(birth), mrthyu ( death ) , jara (old age ) , vyadhi ( disease ) , fear of maintenance and suffering caused by individuals etc
