Decision and doubt sankalpa vikalpa

 the material mind simply functions on the level of decision and doubt. To transcend it, one must give up trying to satisfy the senses and turn the focus of the mind inward. Eventually, by Krsna's grace, the meditation awakens the inner subtle bodies of man-made pranamaya and vijnanamaya. Ultimately it awakens the anandamaya body and that is the point of liberation. At that time, if you have also awakened love for krsna then i guess you are safe. Meanwhile siddhis and mystical occurences flood into awareness and it is time to keep the end goal clearly in the forefront to not become distracted.

The most important turning point is pratyahara or giving up the desire for material sense enjoyment. Dead things.
