My Dear Sarita,
Please accept my blessings.
All glories to Srila Prabhupada.
In a lecture given in London on 29 August 1971 Srila Prabhupada has very nicely answered your question as follows:
"A living entity's name is sarva-gah. Sarva-gah means 'one who can go anywhere he likes.' Just Narada Muni. Narada Muni can travel anywhere he likes, either in the spiritual world or in the material world. So you can also do that. There is possibility. There was a Durvasa Muni, great yogi. Within one year he traveled all over the universe and went to Visnuloka and again came back. That is recorded in the history. So these are
the perfections of life. And how these perfection can be attained? By understanding Krsna. Yasmin vijnate sarvam eva vijnatam bhavanti. The Upanisad says, if you simply understand Krsna, then all these things
can be understood very easily. Krsna consciousness is such
a nice thing."
I hope this meets you in the best of health.
Your ever well-wisher,
Sankarshan Das Adhikari
