Bṛhaspati Said:: One shall bring Prāṇa and Apāna under control by keeping the vital airs inter-connected with fasting. Thereafter, all the sense-organs must be brought under control. The intellect should be restrained within the mind and all (the sense-organs) should be withdrawn. If this Pratyāhāra (withdrawal of the sense-organs) is carried out, know that it is undoubtedly the means of Liberation (mokṣa). Among the sense-organs, the mind is terrible. The transformation of the intellect etc. can be achieved through abstinence from food. A person who undertakes fast attains everlasting benefit. It should be known that fasting is a form of penance. When the intellect and the mind are restrained the knowledge of other things does not arise. When all the defects are destroyed, when the sense-organs are suppressed, the pure soul attains the bliss of Liberation like the fire devoid of fuel. The person conversant with the Yogic practice engages the Kṣetrajña (individual soul) by means of the Yogic exercise, remaining away from all causes and casting off Guṇas, entirely, whether manifest or unmanifest.
