मनः प्रसादः सौम्यत्वं मौनमात्मविनिग्रहः ।भावसंशुद्धिरित्येतत् तपो मानसमुच्यते ॥
manaḥ prasādaḥ saumyatvaṃ maunamātmavinigrahaḥbhāvasaṃśuddhirityetat tapo mānasamucyate
A clear and calm gladness of mind, gentleness, silence, self-control, the purifying of the whole temperament - this is called the askesis of the mind.
Gītā 17·16Here comes in all that quiets or disciplines the rajasic and egoistic nature and all that replaces it by the happy and tranquil principle of good and virtue. This is the askesis of the sattwic dharma so highly prized in the system of the ancient Indian culture. Its greater culmination will be a high purity of the reason and will, an equal soul, a deep peace and calm, a wide sympathy and preparation of oneness, a reflection of the inner soul’s divine gladness in the mind, life and body.
