प्रशान्तमनसं ह्येनं योगिनं सुखमुत्तमम् ।उपैति शान्तरजसं ब्रह्मभूतमकल्मषम् ॥
praśāntamanasaṃ hyenaṃ yoginaṃ sukhamuttamamupaiti śāntarajasaṃ brahmabhūtamakalmaṣam
When the mind is thoroughly quieted, then there comes upon the Yogin the highest, stainless, passionless bliss of the soul that has become the Brahman.
Gītā 6·27
