Hi Casey,
Yes, there is no such thing as “pickling” a living body in order to help it to live longer. Pickling causes living cells to die.
Also, attachment is one of the kleshas, or obstructions, that prevents us from experiencing liberation. It does not actually matter what the attachment is to. It is great to want to live a healthy, long life, but if it becomes an attachment, then it is a klesha (obstruction) standing in the way of liberation, just as fear of death is a klesha.
There are only five kleshas:
- Attachment/ clinging
- Aversion
- The sense of I/ me/ mine
- The fear of death
- Ignorance
Immortality (amrita) is about something much more than attachment or clinging to the physical body and in fact cannot be realised if that clinging is present.
