Everyone and everything will eventually let you down. Make no mistake about this – it’s just a matter of time. Be sure to understand this.
This is not pessimism but reality. You can then enter into life knowlingly. We can enter into love and engage with life out of understanding rather than ignorance.
Know that everything will eventually let you down. You cannot rely on anyone or anything to give you lasting happiness, so dont expect that from people or things. Anything else leads to suffering.
The only exception is the ever-present Self, which of course is no particular object, yet is non-separate from everything. It is all there is. It is the essence of who you are. It is you.
And luckily its nature is sat-chit-ananda.
Therefore take refuge only in the Self.
