Aksara Parabrahman Yoga-Bhagavad Gita Chapter 8 [Attainment of Salvation]
Krishna Said > Shaloka: 15
After attaining Me, the great souls, who are yogis in devotion, never return to this temporary world, which is full of miseries, because they have attained the highest perfection.
Since this temporary material world is full of the miseries of birth, old age, disease and death, naturally he who achieves the highest perfection and attains the supreme planet, Krishnaloka, Goloka Vrndavana, does not wish to return. The supreme planet is described in Vedic literature as beyond our material vision, and it is considered the highest goal. The mahatmas (great souls) receive transcendental messages from the realized devotees and thus gradually develop devotional service in Krishna consciousness and become so absorbed in transcendental service that they no longer desire elevation to any of the material planets, nor do they even want to be transferred to any spiritual planet. They only want Krishna’s association and nothing else. Such great souls in Krishna consciousness attain the highest perfection of life. In other words, they are the supreme souls.
