Tax efficient passive income planning

I fall in 1 cr plus salaried income bracket. so my taxes are high. any income i will earn from dividends or interest will get taxed at slab rates. I have some accumulated money from bonuses general savings etc. over past year and needs to deploy it somewhere. I already have good amount invested in direct stocks, which obviously isn't doing that well at the moment given market correction. also wanted to build eventually 1 lakh per month passive income in relatively less risky investment, 50k Immediately which can be increased so it can fetch 1 lakh per month in few years. whats advisable way to achieve this considering my current tax slab rate issue. (have already done 25 lakhs in senior citizen saving certificate in name of parents, but I don't touch that money). any guidance is welcome, thanks in advance.
