The word Yoga in Sanskrit has several meanings such as: means, meditation, union, fitness, remedy, etc. A yogi can attain eight different perfections or Siddhis to become a perfect Yogi. But Krishna mentions that the practice of Yoga is not for mystic power or better health, but to end this material life and attain the Lord’s abode (Kingdom of God).
yuñjann evaṁ sadātmānaṁ yogī niyata-mānasaḥ
śāntiṁ nirvāṇa-paramāṁ mat-saṁsthām adhigacchati (BG 6.15)
Thus practicing constant control of the body, mind and activities, the mystic transcendentalist, his mind regulated, attains to the kingdom of God [or the abode of Kṛṣṇa] by cessation of material existence.
A person who has realized the true yoga or the union as mentioned by Krishna in the Bhagavad Gita is the true Yogic practitioner, in the path of Bhakti Yoga.
Let us chant the Holy name of the Lord and be the practitioner of true yoga as mentioned in the Bhagavad Gita.
