Perhaps they are not stars, but rather openings in heaven where the love of our lost ones pours through and shines down upon us to let us know they are happy.
The fruit of silence is known only to those with experience. There is gradually born within us in and of our silence itself, something that will draw us on to still greater silence. God leads us into solitude to speak to our heart. Let our hearts be a living altar from which there constantly ascends before God pure prayer, with which all our acts should be imbued.
