By performing pious karma, the limit that we can achieve is elevation to higher planets, where there is a longer life with less disease and less anxieties. But ultimately when the karma is exhausted, we are back in the same situation. And through various yoga processes we can have incredible supernatural powers, we can read people’s minds, we can jump on the sunray and go to the sun planet, we can jump in the Ganga and say a mantra and go to Badrinath without taking those buses where everyone is vomiting and everything, we can say a mantra and create gold, create palaces. By his yogic powers Kardama Muni created a nice aerial mansion for his wife.
And through the perfection of jnana marg, one can attain mukti, liberation. But realizing our eternal instinct of intimate ecstatic love for Krishna and to feel Krishna’s infinite love cannot be attained by our own powers.
Krishna says in Gita, bhaktyä tv ananyayä çakya aham evaà-vidho ‘rjuna BG 11.54, “It is only by undivided devotion, bhakti, that I can be understood as I am.” Out of many people who achieve mukti, and out of many people who achieve these incredible supernatural powers of siddhis, it is very rare to find one who is a pure devotee of the Supreme Personality of Godhead. Only such a person is totally satisfied, because it’s our natural position.
