A consummate yogi, who is perfect in understanding Lord Krsna, as is clearly stated herein (mat-cittah, mat-parah, mat-sthanam) by the Lord Himself, can attain real peace and can ultimately reach His supreme abode, the Krsna-loka known as Goloka Vrndavana. In the Brahma-samhita it is clearly stated (goloka eva nivasaty akhilatma-bhutah) that the Lord, although residing always in His abode called Goloka, is the all-pervading Brahman and the localized Paramatma as well by dint of His superior spiritual energies. No one can reach the spiritual sky or enter into the eternal abode (Vaikuntha Goloka Vrndavana) of the Lord without the proper understanding of Krsna and His plenary expansion Visnu. Therefore a person working in Krsna consciousness is the perfect yogi, because his mind is always absorbed in Krsna's activities. Sa vai manah krsna-padaravindayoh. In the Vedas also we learn: tam eva viditvatimrtyum eti: "One can overcome the path of birth and death only by understanding the Supreme Personality of Godhead, Krsna." In other words, perfection of the yoga system is the attainment of freedom from material existence and not some magical jugglery or gymnastic feats to befool innocent people.
