I think all of the four main categories of yoga go together, whatever age we are in. They are all important:

Bhakti is loving devotion to the divine ideal. With love for divinity and for all beings our minds become pure and prepared for realization. Some great souls such as Mira Bai demonstrate this path.

Jnana is the recognition of our nature as pure consciousness. This is a direct path, of seeing our liberated nature. This is the way of some great souls such as Ramana Maharshi.

Karma is the practical side, acting selflessly for the benefit of all beings. This is such an important path. Only through this path do we know if our practice is genuine. Words are easy, but the deeds on this path prove that there has been real transformation. Some great souls such as Mata Amritanandamayi (Amma) demonstrate this path.

Raja pacifies our minds, concentrates them and gives them the one-pointed focus that we need to succeed. Great souls such as Ramakrishna demonstrate the necessity of this one-pointed mind.

So I think all these yogas together, support each other and help us. May we all attain moksha in this life!
