Yoga-siddhi — The Mystic Perfections and Their Origin in Meditation on the Lord
मनो मयि सुसंयोज्य देहं तदनुवायुना । मद्धारणानुभावेन तत्रात्मा यत्र वै मन: ॥ २१ ॥
mano mayi su-saṁyojya dehaṁ tad-anuvāyunā mad-dhāraṇānubhāvena tatrātmā yatra vai manaḥ
Le yogī qui absorbe entièrement son mental en Moi et, par le souffle subtil qui suit le mental, résorbe aussi le corps matériel en Moi, obtient par la puissance de la méditation sur Moi la perfection mystique grâce à laquelle son corps suit aussitôt son esprit partout où il se rend.
Tad-anuvāyunā indicates the particular subtle air that follows the mind. When the yogī merges this air together with the body and mind in Kṛṣṇa by the potency of meditation on the Lord, his gross material body, like the subtle air, can follow the mind anywhere. This perfection is called mano-javaḥ.
This verse explains that when the mind is firmly fixed on the Lord, the life-air follows the mind, and the body can be brought under control through the potency of meditation (dhāraṇā) on Him.
In the Uddhava-gītā section, Kṛṣṇa instructs Uddhava on devotionally grounded yoga and the mystic perfections, showing that true yogic power rests on concentration upon the Supreme.
Practice daily concentration on the Lord (through japa, prayer, or attentive remembrance), and regulate breath and habits so that your energy follows your chosen focus rather than distractions.
