The process described here is meant to fulfill one’s material desires, not to bring one transcendental knowledge. Therefore this process cannot be accepted as devotional service to the Lord, according to ÅšrÄ«la BhaktisiddhÄnta SarasvatÄ« ṬhÄkura. Despite all such mystic perfections, the material body will ultimately die. Actual eternal youth and happiness are available only on the spiritual platform of Kṛṣṇa consciousness.
