We are not very much hopeful for any lasting pleasure or satisfaction for our deepest cravings within this realm of gross matter.
But actual fact is that this material world is a miserable, negative place, full of danger at every step, duhkhalayam asasvatam, temporary abode of death, birth, disease and old-age, home of suffering and pain only. To come to that platform of understanding of things as they are, that is not a very common thing, and therefore such persons who attain to it, they are described as "great souls":
- mam upetya punar janma
- duhkhalayam asasvatam
- napnuvanti mahatmanah
- samsiddhim paramam gatah
- (BG 8.15)
This verse is spoken by Krishna, or God, Himself in Bhagavad-gita so who can be more final authority? That means that anyone who has understood that the material worlds are places of misery and temporaryness, duhkhalayam asasvatam, they never return here again, and because they are mahatmanah, the great souls, Krishna keeps them with Him, having qualified themselves to escape this nasty place by becoming His pure devotees. So the point is that to make advancement in spiritual life, everything material, unless it is utilized to serve and please Krishna, must be viewed with a pessimistic eye. We are not very much hopeful for any lasting pleasure or satisfaction for our deepest cravings within this realm of gross matter.
You refer to the word "love" several times in your letter, but actual fact is there is no love in this material world. That is false propaganda. What they call "love" here is lust only, desire for personal sense-gratification;
- kama esa krodha esa, rajoguna samudbhavah,
- maha-sano maha-papma, viddhy enam iha vairinam
