yathā sańkalpayed buddhyā
yadā vā mat-paraḥ pumān
mayi satye mano yuñjaḿs
tathā tat samupāśnute
yatha -- by which means; sankalpayet -- one may determine or resolve; buddhya -- by the mind; yada -- when; va -- or; mat-parah -- having faith in Me; puman -- the yogi; mayi -- in Me; satye -- whose desire always becomes truth; manah -- the mind; yunjan -- absorbing; tatha -- by that means; tat -- that very purpose; samupasnute -- he obtains.
In this verse the word yada ("whenever") indicates that by the mystic power called yatha-sankalpa-samsiddhi one will achieve one's objective even if one pursues it at an inauspicious time. Lord Krishna is called satya-sankalpa, or He whose desire, intention, purpose or resolve always comes to pass.
Srila Bhaktisiddhanta Sarasvati Thakura mentions that one should determine to revive one's lost relationship with the Supreme Lord Krishna through the infallible means of devotional service, which can be executed at any time or in any place. There are many books giving proper guidance for achieving Lord Krishna, and the following are mentioned: Srila Jiva Gosvami's Sankalpa-kalpavriksha, Srila Krishnadasa Kaviraja's Sri Govinda-lilamrita, Srila Visvanatha Cakravarti's Sri Krishna-bhavanamrita and Sankalpa-kalpadruma, and Srila Bhaktivinoda Thakura's Sri Gauranga-smarana-mangala. In the modern age, His Divine Grace A. C. Bhaktivedanta Swami Prabhupada has given us over sixty large volumes of transcendental literature, which can fix us firmly on the path back home, back to Godhead. Our sankalpa, or determination, should be practical and not useless. We should resolve to make a permanent solution to the problems of life by going back home, back to Godhead.
